Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492226, here are decompositions:

13 + 31492213 = 31492226
193 + 31492033 = 31492226
313 + 31491913 = 31492226
433 + 31491793 = 31492226
439 + 31491787 = 31492226
499 + 31491727 = 31492226
547 + 31491679 = 31492226
607 + 31491619 = 31492226

Showing the first eight; more decompositions exist.
