Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494204, here are decompositions:

43 + 31494161 = 31494204
47 + 31494157 = 31494204
61 + 31494143 = 31494204
107 + 31494097 = 31494204
113 + 31494091 = 31494204
151 + 31494053 = 31494204
163 + 31494041 = 31494204
263 + 31493941 = 31494204

Showing the first eight; more decompositions exist.
