Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606634, here are decompositions:

97 + 31606537 = 31606634
211 + 31606423 = 31606634
223 + 31606411 = 31606634
337 + 31606297 = 31606634
373 + 31606261 = 31606634
547 + 31606087 = 31606634
757 + 31605877 = 31606634
811 + 31605823 = 31606634

Showing the first eight; more decompositions exist.
