Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537806, here are decompositions:

59 + 31537747 = 31537806
89 + 31537717 = 31537806
197 + 31537609 = 31537806
233 + 31537573 = 31537806
263 + 31537543 = 31537806
337 + 31537469 = 31537806
373 + 31537433 = 31537806
397 + 31537409 = 31537806

Showing the first eight; more decompositions exist.
