Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552258, here are decompositions:

5 + 31552253 = 31552258
29 + 31552229 = 31552258
47 + 31552211 = 31552258
131 + 31552127 = 31552258
239 + 31552019 = 31552258
281 + 31551977 = 31552258
317 + 31551941 = 31552258
401 + 31551857 = 31552258

Showing the first eight; more decompositions exist.
