Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529672, here are decompositions:

3 + 31529669 = 31529672
43 + 31529629 = 31529672
79 + 31529593 = 31529672
151 + 31529521 = 31529672
193 + 31529479 = 31529672
241 + 31529431 = 31529672
313 + 31529359 = 31529672
523 + 31529149 = 31529672

Showing the first eight; more decompositions exist.
