Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552898, here are decompositions:

7 + 31552891 = 31552898
19 + 31552879 = 31552898
67 + 31552831 = 31552898
151 + 31552747 = 31552898
277 + 31552621 = 31552898
409 + 31552489 = 31552898
547 + 31552351 = 31552898
661 + 31552237 = 31552898

Showing the first eight; more decompositions exist.
