Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510654, here are decompositions:

23 + 31510631 = 31510654
101 + 31510553 = 31510654
113 + 31510541 = 31510654
137 + 31510517 = 31510654
167 + 31510487 = 31510654
251 + 31510403 = 31510654
257 + 31510397 = 31510654
431 + 31510223 = 31510654

Showing the first eight; more decompositions exist.
