Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529726, here are decompositions:

97 + 31529629 = 31529726
103 + 31529623 = 31529726
313 + 31529413 = 31529726
367 + 31529359 = 31529726
373 + 31529353 = 31529726
379 + 31529347 = 31529726
457 + 31529269 = 31529726
577 + 31529149 = 31529726

Showing the first eight; more decompositions exist.
