Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678578, here are decompositions:

  • 59 + 8678519 = 8678578
  • 71 + 8678507 = 8678578
  • 131 + 8678447 = 8678578
  • 179 + 8678399 = 8678578
  • 239 + 8678339 = 8678578
  • 431 + 8678147 = 8678578
  • 449 + 8678129 = 8678578
  • 509 + 8678069 = 8678578

Showing the first eight; more decompositions exist.
