Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492594, here are decompositions:

17 + 31492577 = 31492594
41 + 31492553 = 31492594
53 + 31492541 = 31492594
101 + 31492493 = 31492594
173 + 31492421 = 31492594
191 + 31492403 = 31492594
257 + 31492337 = 31492594
317 + 31492277 = 31492594

Showing the first eight; more decompositions exist.
