Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528582, here are decompositions:

3 + 31528579 = 31528582
23 + 31528559 = 31528582
83 + 31528499 = 31528582
131 + 31528451 = 31528582
149 + 31528433 = 31528582
233 + 31528349 = 31528582
269 + 31528313 = 31528582
353 + 31528229 = 31528582

Showing the first eight; more decompositions exist.
