Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529580, here are decompositions:

13 + 31529567 = 31529580
23 + 31529557 = 31529580
29 + 31529551 = 31529580
41 + 31529539 = 31529580
59 + 31529521 = 31529580
73 + 31529507 = 31529580
101 + 31529479 = 31529580
109 + 31529471 = 31529580

Showing the first eight; more decompositions exist.
