Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528684, here are decompositions:

71 + 31528613 = 31528684
137 + 31528547 = 31528684
233 + 31528451 = 31528684
251 + 31528433 = 31528684
311 + 31528373 = 31528684
347 + 31528337 = 31528684
401 + 31528283 = 31528684
443 + 31528241 = 31528684

Showing the first eight; more decompositions exist.
