Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496626, here are decompositions:

53 + 31496573 = 31496626
59 + 31496567 = 31496626
89 + 31496537 = 31496626
107 + 31496519 = 31496626
137 + 31496489 = 31496626
197 + 31496429 = 31496626
257 + 31496369 = 31496626
503 + 31496123 = 31496626

Showing the first eight; more decompositions exist.
