Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552486, here are decompositions:

83 + 31552403 = 31552486
233 + 31552253 = 31552486
257 + 31552229 = 31552486
293 + 31552193 = 31552486
347 + 31552139 = 31552486
359 + 31552127 = 31552486
467 + 31552019 = 31552486
509 + 31551977 = 31552486

Showing the first eight; more decompositions exist.
