Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494292, here are decompositions:

29 + 31494263 = 31494292
113 + 31494179 = 31494292
131 + 31494161 = 31494292
149 + 31494143 = 31494292
173 + 31494119 = 31494292
239 + 31494053 = 31494292
251 + 31494041 = 31494292
293 + 31493999 = 31494292

Showing the first eight; more decompositions exist.
