Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528486, here are decompositions:

53 + 31528433 = 31528486
113 + 31528373 = 31528486
137 + 31528349 = 31528486
149 + 31528337 = 31528486
173 + 31528313 = 31528486
257 + 31528229 = 31528486
317 + 31528169 = 31528486
359 + 31528127 = 31528486

Showing the first eight; more decompositions exist.
