Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497848, here are decompositions:

97 + 31497751 = 31497848
127 + 31497721 = 31497848
181 + 31497667 = 31497848
211 + 31497637 = 31497848
271 + 31497577 = 31497848
307 + 31497541 = 31497848
379 + 31497469 = 31497848
439 + 31497409 = 31497848

Showing the first eight; more decompositions exist.
