Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492612, here are decompositions:

59 + 31492553 = 31492612
71 + 31492541 = 31492612
83 + 31492529 = 31492612
191 + 31492421 = 31492612
293 + 31492319 = 31492612
353 + 31492259 = 31492612
449 + 31492163 = 31492612
521 + 31492091 = 31492612

Showing the first eight; more decompositions exist.
