Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527708, here are decompositions:

5 + 31527703 = 31527708
7 + 31527701 = 31527708
11 + 31527697 = 31527708
19 + 31527689 = 31527708
31 + 31527677 = 31527708
131 + 31527577 = 31527708
139 + 31527569 = 31527708
167 + 31527541 = 31527708

Showing the first eight; more decompositions exist.
