Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552282, here are decompositions:

11 + 31552271 = 31552282
29 + 31552253 = 31552282
53 + 31552229 = 31552282
71 + 31552211 = 31552282
89 + 31552193 = 31552282
233 + 31552049 = 31552282
263 + 31552019 = 31552282
479 + 31551803 = 31552282

Showing the first eight; more decompositions exist.
