Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606346, here are decompositions:

3 + 31606343 = 31606346
7 + 31606339 = 31606346
67 + 31606279 = 31606346
433 + 31605913 = 31606346
523 + 31605823 = 31606346
619 + 31605727 = 31606346
727 + 31605619 = 31606346
769 + 31605577 = 31606346

Showing the first eight; more decompositions exist.
