Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606682, here are decompositions:

31 + 31606651 = 31606682
103 + 31606579 = 31606682
139 + 31606543 = 31606682
271 + 31606411 = 31606682
313 + 31606369 = 31606682
421 + 31606261 = 31606682
631 + 31606051 = 31606682
769 + 31605913 = 31606682

Showing the first eight; more decompositions exist.
