Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480548, here are decompositions:

19 + 31480529 = 31480548
41 + 31480507 = 31480548
107 + 31480441 = 31480548
157 + 31480391 = 31480548
167 + 31480381 = 31480548
179 + 31480369 = 31480548
181 + 31480367 = 31480548
199 + 31480349 = 31480548

Showing the first eight; more decompositions exist.
