Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559624, here are decompositions:

157 + 31559467 = 31559624
181 + 31559443 = 31559624
211 + 31559413 = 31559624
223 + 31559401 = 31559624
241 + 31559383 = 31559624
307 + 31559317 = 31559624
373 + 31559251 = 31559624
463 + 31559161 = 31559624

Showing the first eight; more decompositions exist.
