Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492508, here are decompositions:

31 + 31492477 = 31492508
37 + 31492471 = 31492508
79 + 31492429 = 31492508
109 + 31492399 = 31492508
139 + 31492369 = 31492508
457 + 31492051 = 31492508
811 + 31491697 = 31492508
829 + 31491679 = 31492508

Showing the first eight; more decompositions exist.
