Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492958, here are decompositions:

37 + 31492921 = 31492958
109 + 31492849 = 31492958
157 + 31492801 = 31492958
181 + 31492777 = 31492958
307 + 31492651 = 31492958
331 + 31492627 = 31492958
421 + 31492537 = 31492958
487 + 31492471 = 31492958

Showing the first eight; more decompositions exist.
