Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504712, here are decompositions:

61 + 31504651 = 31504712
139 + 31504573 = 31504712
409 + 31504303 = 31504712
523 + 31504189 = 31504712
661 + 31504051 = 31504712
739 + 31503973 = 31504712
751 + 31503961 = 31504712
829 + 31503883 = 31504712

Showing the first eight; more decompositions exist.
