Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528692, here are decompositions:

23 + 31528669 = 31528692
59 + 31528633 = 31528692
71 + 31528621 = 31528692
79 + 31528613 = 31528692
113 + 31528579 = 31528692
191 + 31528501 = 31528692
193 + 31528499 = 31528692
233 + 31528459 = 31528692

Showing the first eight; more decompositions exist.
