Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552838, here are decompositions:

7 + 31552831 = 31552838
157 + 31552681 = 31552838
199 + 31552639 = 31552838
349 + 31552489 = 31552838
409 + 31552429 = 31552838
487 + 31552351 = 31552838
601 + 31552237 = 31552838
631 + 31552207 = 31552838

Showing the first eight; more decompositions exist.
