Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494334, here are decompositions:

41 + 31494293 = 31494334
71 + 31494263 = 31494334
173 + 31494161 = 31494334
191 + 31494143 = 31494334
251 + 31494083 = 31494334
281 + 31494053 = 31494334
293 + 31494041 = 31494334
383 + 31493951 = 31494334

Showing the first eight; more decompositions exist.
