Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606604, here are decompositions:

61 + 31606543 = 31606604
67 + 31606537 = 31606604
181 + 31606423 = 31606604
193 + 31606411 = 31606604
223 + 31606381 = 31606604
307 + 31606297 = 31606604
691 + 31605913 = 31606604
727 + 31605877 = 31606604

Showing the first eight; more decompositions exist.
