Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552366, here are decompositions:

113 + 31552253 = 31552366
137 + 31552229 = 31552366
173 + 31552193 = 31552366
227 + 31552139 = 31552366
239 + 31552127 = 31552366
317 + 31552049 = 31552366
347 + 31552019 = 31552366
389 + 31551977 = 31552366

Showing the first eight; more decompositions exist.
