Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492334, here are decompositions:

73 + 31492261 = 31492334
241 + 31492093 = 31492334
283 + 31492051 = 31492334
421 + 31491913 = 31492334
541 + 31491793 = 31492334
547 + 31491787 = 31492334
607 + 31491727 = 31492334
673 + 31491661 = 31492334

Showing the first eight; more decompositions exist.
