Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528532, here are decompositions:

31 + 31528501 = 31528532
73 + 31528459 = 31528532
241 + 31528291 = 31528532
421 + 31528111 = 31528532
439 + 31528093 = 31528532
463 + 31528069 = 31528532
601 + 31527931 = 31528532
619 + 31527913 = 31528532

Showing the first eight; more decompositions exist.
