Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61618, here are decompositions:

  • 5 + 61613 = 61618
  • 59 + 61559 = 61618
  • 71 + 61547 = 61618
  • 107 + 61511 = 61618
  • 131 + 61487 = 61618
  • 149 + 61469 = 61618
  • 239 + 61379 = 61618
  • 449 + 61169 = 61618

Showing the first eight; more decompositions exist.
