Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552908, here are decompositions:

17 + 31552891 = 31552908
29 + 31552879 = 31552908
61 + 31552847 = 31552908
181 + 31552727 = 31552908
199 + 31552709 = 31552908
227 + 31552681 = 31552908
269 + 31552639 = 31552908
419 + 31552489 = 31552908

Showing the first eight; more decompositions exist.
