Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527704, here are decompositions:

3 + 31527701 = 31527704
7 + 31527697 = 31527704
127 + 31527577 = 31527704
163 + 31527541 = 31527704
181 + 31527523 = 31527704
223 + 31527481 = 31527704
457 + 31527247 = 31527704
547 + 31527157 = 31527704

Showing the first eight; more decompositions exist.
