Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991490, here are decompositions:

  • 19 + 4294991471 = 4294991490
  • 29 + 4294991461 = 4294991490
  • 43 + 4294991447 = 4294991490
  • 47 + 4294991443 = 4294991490
  • 59 + 4294991431 = 4294991490
  • 61 + 4294991429 = 4294991490
  • 67 + 4294991423 = 4294991490
  • 73 + 4294991417 = 4294991490

Showing the first eight; more decompositions exist.
