Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606698, here are decompositions:

7 + 31606691 = 31606698
17 + 31606681 = 31606698
31 + 31606667 = 31606698
37 + 31606661 = 31606698
41 + 31606657 = 31606698
47 + 31606651 = 31606698
139 + 31606559 = 31606698
157 + 31606541 = 31606698

Showing the first eight; more decompositions exist.
