Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552588, here are decompositions:

101 + 31552487 = 31552588
167 + 31552421 = 31552588
317 + 31552271 = 31552588
359 + 31552229 = 31552588
449 + 31552139 = 31552588
461 + 31552127 = 31552588
569 + 31552019 = 31552588
647 + 31551941 = 31552588

Showing the first eight; more decompositions exist.
