Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606670, here are decompositions:

3 + 31606667 = 31606670
13 + 31606657 = 31606670
19 + 31606651 = 31606670
127 + 31606543 = 31606670
241 + 31606429 = 31606670
283 + 31606387 = 31606670
331 + 31606339 = 31606670
373 + 31606297 = 31606670

Showing the first eight; more decompositions exist.
