Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528634, here are decompositions:

13 + 31528621 = 31528634
61 + 31528573 = 31528634
103 + 31528531 = 31528634
271 + 31528363 = 31528634
307 + 31528327 = 31528634
367 + 31528267 = 31528634
421 + 31528213 = 31528634
463 + 31528171 = 31528634

Showing the first eight; more decompositions exist.
