Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529732, here are decompositions:

61 + 31529671 = 31529732
103 + 31529629 = 31529732
109 + 31529623 = 31529732
139 + 31529593 = 31529732
181 + 31529551 = 31529732
193 + 31529539 = 31529732
211 + 31529521 = 31529732
373 + 31529359 = 31529732

Showing the first eight; more decompositions exist.
