Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494184, here are decompositions:

5 + 31494179 = 31494184
23 + 31494161 = 31494184
41 + 31494143 = 31494184
101 + 31494083 = 31494184
131 + 31494053 = 31494184
233 + 31493951 = 31494184
257 + 31493927 = 31494184
401 + 31493783 = 31494184

Showing the first eight; more decompositions exist.
