Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590756, here are decompositions:

17 + 31590739 = 31590756
19 + 31590737 = 31590756
23 + 31590733 = 31590756
73 + 31590683 = 31590756
89 + 31590667 = 31590756
97 + 31590659 = 31590756
107 + 31590649 = 31590756
139 + 31590617 = 31590756

Showing the first eight; more decompositions exist.
