Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552308, here are decompositions:

5 + 31552303 = 31552308
37 + 31552271 = 31552308
71 + 31552237 = 31552308
79 + 31552229 = 31552308
97 + 31552211 = 31552308
101 + 31552207 = 31552308
181 + 31552127 = 31552308
239 + 31552069 = 31552308

Showing the first eight; more decompositions exist.
