Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606702, here are decompositions:

5 + 31606697 = 31606702
11 + 31606691 = 31606702
41 + 31606661 = 31606702
59 + 31606643 = 31606702
173 + 31606529 = 31606702
233 + 31606469 = 31606702
359 + 31606343 = 31606702
383 + 31606319 = 31606702

Showing the first eight; more decompositions exist.
