Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522334, here are decompositions:

3 + 31522331 = 31522334
7 + 31522327 = 31522334
37 + 31522297 = 31522334
127 + 31522207 = 31522334
313 + 31522021 = 31522334
541 + 31521793 = 31522334
661 + 31521673 = 31522334
691 + 31521643 = 31522334

Showing the first eight; more decompositions exist.
