Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528562, here are decompositions:

3 + 31528559 = 31528562
31 + 31528531 = 31528562
61 + 31528501 = 31528562
103 + 31528459 = 31528562
199 + 31528363 = 31528562
271 + 31528291 = 31528562
283 + 31528279 = 31528562
349 + 31528213 = 31528562

Showing the first eight; more decompositions exist.
