Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492010, here are decompositions:

97 + 31491913 = 31492010
223 + 31491787 = 31492010
283 + 31491727 = 31492010
313 + 31491697 = 31492010
331 + 31491679 = 31492010
349 + 31491661 = 31492010
373 + 31491637 = 31492010
397 + 31491613 = 31492010

Showing the first eight; more decompositions exist.
