Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566698, here are decompositions:

67 + 31566631 = 31566698
109 + 31566589 = 31566698
139 + 31566559 = 31566698
151 + 31566547 = 31566698
157 + 31566541 = 31566698
181 + 31566517 = 31566698
211 + 31566487 = 31566698
271 + 31566427 = 31566698

Showing the first eight; more decompositions exist.
