Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460750, here are decompositions:

  • 7 + 31460743 = 31460750
  • 73 + 31460677 = 31460750
  • 103 + 31460647 = 31460750
  • 199 + 31460551 = 31460750
  • 241 + 31460509 = 31460750
  • 337 + 31460413 = 31460750
  • 421 + 31460329 = 31460750
  • 457 + 31460293 = 31460750

Showing the first eight; more decompositions exist.
