Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537766, here are decompositions:

19 + 31537747 = 31537766
79 + 31537687 = 31537766
157 + 31537609 = 31537766
163 + 31537603 = 31537766
193 + 31537573 = 31537766
223 + 31537543 = 31537766
439 + 31537327 = 31537766
457 + 31537309 = 31537766

Showing the first eight; more decompositions exist.
