Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529024, here are decompositions:

31 + 31528993 = 31529024
181 + 31528843 = 31529024
193 + 31528831 = 31529024
211 + 31528813 = 31529024
223 + 31528801 = 31529024
283 + 31528741 = 31529024
523 + 31528501 = 31529024
577 + 31528447 = 31529024

Showing the first eight; more decompositions exist.
