Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460162, here are decompositions:

109 + 31460053 = 31460162
163 + 31459999 = 31460162
199 + 31459963 = 31460162
271 + 31459891 = 31460162
313 + 31459849 = 31460162
439 + 31459723 = 31460162
541 + 31459621 = 31460162
823 + 31459339 = 31460162

Showing the first eight; more decompositions exist.
