Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147510770, here are decompositions:

  • 3 + 2147510767 = 2147510770
  • 29 + 2147510741 = 2147510770
  • 59 + 2147510711 = 2147510770
  • 137 + 2147510633 = 2147510770
  • 179 + 2147510591 = 2147510770
  • 191 + 2147510579 = 2147510770
  • 233 + 2147510537 = 2147510770
  • 269 + 2147510501 = 2147510770

Showing the first eight; more decompositions exist.
