Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480632, here are decompositions:

11 + 31480621 = 31480632
103 + 31480529 = 31480632
191 + 31480441 = 31480632
199 + 31480433 = 31480632
241 + 31480391 = 31480632
251 + 31480381 = 31480632
263 + 31480369 = 31480632
283 + 31480349 = 31480632

Showing the first eight; more decompositions exist.
