Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493348, here are decompositions:

97 + 31493251 = 31493348
157 + 31493191 = 31493348
331 + 31493017 = 31493348
499 + 31492849 = 31493348
547 + 31492801 = 31493348
571 + 31492777 = 31493348
577 + 31492771 = 31493348
751 + 31492597 = 31493348

Showing the first eight; more decompositions exist.
