Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529462, here are decompositions:

31 + 31529431 = 31529462
103 + 31529359 = 31529462
109 + 31529353 = 31529462
193 + 31529269 = 31529462
313 + 31529149 = 31529462
373 + 31529089 = 31529462
409 + 31529053 = 31529462
619 + 31528843 = 31529462

Showing the first eight; more decompositions exist.
