Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493334, here are decompositions:

11 + 31493323 = 31493334
13 + 31493321 = 31493334
43 + 31493291 = 31493334
83 + 31493251 = 31493334
163 + 31493171 = 31493334
181 + 31493153 = 31493334
251 + 31493083 = 31493334
277 + 31493057 = 31493334

Showing the first eight; more decompositions exist.
