Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552270, here are decompositions:

17 + 31552253 = 31552270
41 + 31552229 = 31552270
59 + 31552211 = 31552270
131 + 31552139 = 31552270
251 + 31552019 = 31552270
293 + 31551977 = 31552270
311 + 31551959 = 31552270
443 + 31551827 = 31552270

Showing the first eight; more decompositions exist.
