Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147437604, here are decompositions:

  • 3 + 2147437601 = 2147437604
  • 73 + 2147437531 = 2147437604
  • 157 + 2147437447 = 2147437604
  • 313 + 2147437291 = 2147437604
  • 337 + 2147437267 = 2147437604
  • 421 + 2147437183 = 2147437604
  • 457 + 2147437147 = 2147437604
  • 577 + 2147437027 = 2147437604

Showing the first eight; more decompositions exist.
