Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595544, here are decompositions:

61 + 31595483 = 31595544
137 + 31595407 = 31595544
151 + 31595393 = 31595544
157 + 31595387 = 31595544
173 + 31595371 = 31595544
181 + 31595363 = 31595544
271 + 31595273 = 31595544
293 + 31595251 = 31595544

Showing the first eight; more decompositions exist.
