Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529702, here are decompositions:

31 + 31529671 = 31529702
73 + 31529629 = 31529702
79 + 31529623 = 31529702
109 + 31529593 = 31529702
151 + 31529551 = 31529702
163 + 31529539 = 31529702
181 + 31529521 = 31529702
223 + 31529479 = 31529702

Showing the first eight; more decompositions exist.
