Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528414, here are decompositions:

41 + 31528373 = 31528414
101 + 31528313 = 31528414
131 + 31528283 = 31528414
173 + 31528241 = 31528414
257 + 31528157 = 31528414
263 + 31528151 = 31528414
293 + 31528121 = 31528414
311 + 31528103 = 31528414

Showing the first eight; more decompositions exist.
