Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539944, here are decompositions:

13 + 31539931 = 31539944
43 + 31539901 = 31539944
127 + 31539817 = 31539944
181 + 31539763 = 31539944
283 + 31539661 = 31539944
421 + 31539523 = 31539944
523 + 31539421 = 31539944
577 + 31539367 = 31539944

Showing the first eight; more decompositions exist.
