Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492310, here are decompositions:

67 + 31492243 = 31492310
97 + 31492213 = 31492310
229 + 31492081 = 31492310
277 + 31492033 = 31492310
397 + 31491913 = 31492310
523 + 31491787 = 31492310
613 + 31491697 = 31492310
631 + 31491679 = 31492310

Showing the first eight; more decompositions exist.
