Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552326, here are decompositions:

17 + 31552309 = 31552326
23 + 31552303 = 31552326
73 + 31552253 = 31552326
89 + 31552237 = 31552326
97 + 31552229 = 31552326
199 + 31552127 = 31552326
257 + 31552069 = 31552326
269 + 31552057 = 31552326

Showing the first eight; more decompositions exist.
