Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494202, here are decompositions:

23 + 31494179 = 31494202
41 + 31494161 = 31494202
59 + 31494143 = 31494202
83 + 31494119 = 31494202
149 + 31494053 = 31494202
251 + 31493951 = 31494202
293 + 31493909 = 31494202
419 + 31493783 = 31494202

Showing the first eight; more decompositions exist.
