Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493502, here are decompositions:

59 + 31493443 = 31493502
83 + 31493419 = 31493502
149 + 31493353 = 31493502
163 + 31493339 = 31493502
179 + 31493323 = 31493502
181 + 31493321 = 31493502
211 + 31493291 = 31493502
251 + 31493251 = 31493502

Showing the first eight; more decompositions exist.
