Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528062, here are decompositions:

43 + 31528019 = 31528062
61 + 31528001 = 31528062
131 + 31527931 = 31528062
149 + 31527913 = 31528062
233 + 31527829 = 31528062
281 + 31527781 = 31528062
353 + 31527709 = 31528062
359 + 31527703 = 31528062

Showing the first eight; more decompositions exist.
