Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530236, here are decompositions:

139 + 31530097 = 31530236
193 + 31530043 = 31530236
313 + 31529923 = 31530236
337 + 31529899 = 31530236
487 + 31529749 = 31530236
607 + 31529629 = 31530236
613 + 31529623 = 31530236
643 + 31529593 = 31530236

Showing the first eight; more decompositions exist.
