Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502426, here are decompositions:

73 + 31502353 = 31502426
97 + 31502329 = 31502426
139 + 31502287 = 31502426
157 + 31502269 = 31502426
313 + 31502113 = 31502426
547 + 31501879 = 31502426
577 + 31501849 = 31502426
607 + 31501819 = 31502426

Showing the first eight; more decompositions exist.
