Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493324, here are decompositions:

3 + 31493321 = 31493324
73 + 31493251 = 31493324
193 + 31493131 = 31493324
241 + 31493083 = 31493324
271 + 31493053 = 31493324
277 + 31493047 = 31493324
307 + 31493017 = 31493324
487 + 31492837 = 31493324

Showing the first eight; more decompositions exist.
