Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528694, here are decompositions:

61 + 31528633 = 31528694
73 + 31528621 = 31528694
163 + 31528531 = 31528694
193 + 31528501 = 31528694
331 + 31528363 = 31528694
367 + 31528327 = 31528694
487 + 31528207 = 31528694
523 + 31528171 = 31528694

Showing the first eight; more decompositions exist.
