Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567750, here are decompositions:

41 + 31567709 = 31567750
101 + 31567649 = 31567750
107 + 31567643 = 31567750
113 + 31567637 = 31567750
131 + 31567619 = 31567750
191 + 31567559 = 31567750
197 + 31567553 = 31567750
239 + 31567511 = 31567750

Showing the first eight; more decompositions exist.
