Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552522, here are decompositions:

101 + 31552421 = 31552522
251 + 31552271 = 31552522
269 + 31552253 = 31552522
293 + 31552229 = 31552522
311 + 31552211 = 31552522
383 + 31552139 = 31552522
503 + 31552019 = 31552522
563 + 31551959 = 31552522

Showing the first eight; more decompositions exist.
