Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529048, here are decompositions:

79 + 31528969 = 31529048
139 + 31528909 = 31529048
241 + 31528807 = 31529048
307 + 31528741 = 31529048
379 + 31528669 = 31529048
547 + 31528501 = 31529048
601 + 31528447 = 31529048
757 + 31528291 = 31529048

Showing the first eight; more decompositions exist.
