Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524398, here are decompositions:

67 + 31524331 = 31524398
97 + 31524301 = 31524398
127 + 31524271 = 31524398
307 + 31524091 = 31524398
349 + 31524049 = 31524398
457 + 31523941 = 31524398
547 + 31523851 = 31524398
691 + 31523707 = 31524398

Showing the first eight; more decompositions exist.
