Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606292, here are decompositions:

13 + 31606279 = 31606292
31 + 31606261 = 31606292
241 + 31606051 = 31606292
379 + 31605913 = 31606292
673 + 31605619 = 31606292
709 + 31605583 = 31606292
853 + 31605439 = 31606292
1021 + 31605271 = 31606292

Showing the first eight; more decompositions exist.
