Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493692, here are decompositions:

3 + 31493689 = 31493692
173 + 31493519 = 31493692
179 + 31493513 = 31493692
353 + 31493339 = 31493692
401 + 31493291 = 31493692
443 + 31493249 = 31493692
491 + 31493201 = 31493692
521 + 31493171 = 31493692

Showing the first eight; more decompositions exist.
