Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524098, here are decompositions:

7 + 31524091 = 31524098
157 + 31523941 = 31524098
181 + 31523917 = 31524098
337 + 31523761 = 31524098
349 + 31523749 = 31524098
439 + 31523659 = 31524098
499 + 31523599 = 31524098
577 + 31523521 = 31524098

Showing the first eight; more decompositions exist.
