Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526508, here are decompositions:

5 + 31526503 = 31526508
11 + 31526497 = 31526508
19 + 31526489 = 31526508
31 + 31526477 = 31526508
89 + 31526419 = 31526508
137 + 31526371 = 31526508
149 + 31526359 = 31526508
157 + 31526351 = 31526508

Showing the first eight; more decompositions exist.
