Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492654, here are decompositions:

3 + 31492651 = 31492654
101 + 31492553 = 31492654
113 + 31492541 = 31492654
233 + 31492421 = 31492654
251 + 31492403 = 31492654
317 + 31492337 = 31492654
491 + 31492163 = 31492654
563 + 31492091 = 31492654

Showing the first eight; more decompositions exist.
