Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543744, here are decompositions:

  • 47 + 31543697 = 31543744
  • 53 + 31543691 = 31543744
  • 83 + 31543661 = 31543744
  • 101 + 31543643 = 31543744
  • 173 + 31543571 = 31543744
  • 263 + 31543481 = 31543744
  • 293 + 31543451 = 31543744
  • 347 + 31543397 = 31543744

Showing the first eight; more decompositions exist.
