Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498548, here are decompositions:

7 + 31498541 = 31498548
19 + 31498529 = 31498548
31 + 31498517 = 31498548
79 + 31498469 = 31498548
127 + 31498421 = 31498548
181 + 31498367 = 31498548
199 + 31498349 = 31498548
241 + 31498307 = 31498548

Showing the first eight; more decompositions exist.
