Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486124, here are decompositions:

3 + 31486121 = 31486124
37 + 31486087 = 31486124
151 + 31485973 = 31486124
193 + 31485931 = 31486124
367 + 31485757 = 31486124
463 + 31485661 = 31486124
541 + 31485583 = 31486124
727 + 31485397 = 31486124

Showing the first eight; more decompositions exist.
