Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957442, here are decompositions:

  • 3 + 4294957439 = 4294957442
  • 43 + 4294957399 = 4294957442
  • 73 + 4294957369 = 4294957442
  • 541 + 4294956901 = 4294957442
  • 613 + 4294956829 = 4294957442
  • 691 + 4294956751 = 4294957442
  • 829 + 4294956613 = 4294957442
  • 1291 + 4294956151 = 4294957442

Showing the first eight; more decompositions exist.
