Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461086, here are decompositions:

37 + 31461049 = 31461086
73 + 31461013 = 31461086
79 + 31461007 = 31461086
109 + 31460977 = 31461086
157 + 31460929 = 31461086
277 + 31460809 = 31461086
409 + 31460677 = 31461086
439 + 31460647 = 31461086

Showing the first eight; more decompositions exist.
