Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492024, here are decompositions:

41 + 31491983 = 31492024
107 + 31491917 = 31492024
131 + 31491893 = 31492024
233 + 31491791 = 31492024
461 + 31491563 = 31492024
467 + 31491557 = 31492024
503 + 31491521 = 31492024
563 + 31491461 = 31492024

Showing the first eight; more decompositions exist.
