Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493504, here are decompositions:

37 + 31493467 = 31493504
61 + 31493443 = 31493504
127 + 31493377 = 31493504
151 + 31493353 = 31493504
157 + 31493347 = 31493504
181 + 31493323 = 31493504
313 + 31493191 = 31493504
373 + 31493131 = 31493504

Showing the first eight; more decompositions exist.
