Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552508, here are decompositions:

19 + 31552489 = 31552508
79 + 31552429 = 31552508
157 + 31552351 = 31552508
199 + 31552309 = 31552508
271 + 31552237 = 31552508
439 + 31552069 = 31552508
571 + 31551937 = 31552508
607 + 31551901 = 31552508

Showing the first eight; more decompositions exist.
