Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624892, here are decompositions:

31 + 31624861 = 31624892
43 + 31624849 = 31624892
109 + 31624783 = 31624892
139 + 31624753 = 31624892
151 + 31624741 = 31624892
193 + 31624699 = 31624892
463 + 31624429 = 31624892
571 + 31624321 = 31624892

Showing the first eight; more decompositions exist.
