Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567738, here are decompositions:

29 + 31567709 = 31567738
89 + 31567649 = 31567738
101 + 31567637 = 31567738
179 + 31567559 = 31567738
227 + 31567511 = 31567738
311 + 31567427 = 31567738
467 + 31567271 = 31567738
647 + 31567091 = 31567738

Showing the first eight; more decompositions exist.
