Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529632, here are decompositions:

3 + 31529629 = 31529632
311 + 31529321 = 31529632
353 + 31529279 = 31529632
359 + 31529273 = 31529632
383 + 31529249 = 31529632
389 + 31529243 = 31529632
419 + 31529213 = 31529632
809 + 31528823 = 31529632

Showing the first eight; more decompositions exist.
