Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543548, here are decompositions:

  • 5 + 31543543 = 31543548
  • 17 + 31543531 = 31543548
  • 19 + 31543529 = 31543548
  • 59 + 31543489 = 31543548
  • 67 + 31543481 = 31543548
  • 97 + 31543451 = 31543548
  • 151 + 31543397 = 31543548
  • 199 + 31543349 = 31543548

Showing the first eight; more decompositions exist.
