Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528592, here are decompositions:

13 + 31528579 = 31528592
19 + 31528573 = 31528592
61 + 31528531 = 31528592
229 + 31528363 = 31528592
313 + 31528279 = 31528592
379 + 31528213 = 31528592
421 + 31528171 = 31528592
499 + 31528093 = 31528592

Showing the first eight; more decompositions exist.
