Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467838, here are decompositions:

  • 37 + 2147467801 = 2147467838
  • 79 + 2147467759 = 2147467838
  • 127 + 2147467711 = 2147467838
  • 199 + 2147467639 = 2147467838
  • 211 + 2147467627 = 2147467838
  • 367 + 2147467471 = 2147467838
  • 499 + 2147467339 = 2147467838
  • 577 + 2147467261 = 2147467838

Showing the first eight; more decompositions exist.
