Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525626, here are decompositions:

17 + 31525609 = 31525626
19 + 31525607 = 31525626
23 + 31525603 = 31525626
37 + 31525589 = 31525626
59 + 31525567 = 31525626
73 + 31525553 = 31525626
89 + 31525537 = 31525626
127 + 31525499 = 31525626

Showing the first eight; more decompositions exist.
