Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537736, here are decompositions:

19 + 31537717 = 31537736
127 + 31537609 = 31537736
163 + 31537573 = 31537736
193 + 31537543 = 31537736
229 + 31537507 = 31537736
397 + 31537339 = 31537736
409 + 31537327 = 31537736
463 + 31537273 = 31537736

Showing the first eight; more decompositions exist.
