Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574102, here are decompositions:

3 + 31574099 = 31574102
31 + 31574071 = 31574102
61 + 31574041 = 31574102
103 + 31573999 = 31574102
271 + 31573831 = 31574102
283 + 31573819 = 31574102
349 + 31573753 = 31574102
463 + 31573639 = 31574102

Showing the first eight; more decompositions exist.
