Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528494, here are decompositions:

43 + 31528451 = 31528494
47 + 31528447 = 31528494
61 + 31528433 = 31528494
131 + 31528363 = 31528494
157 + 31528337 = 31528494
167 + 31528327 = 31528494
181 + 31528313 = 31528494
211 + 31528283 = 31528494

Showing the first eight; more decompositions exist.
