Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527716, here are decompositions:

7 + 31527709 = 31527716
13 + 31527703 = 31527716
19 + 31527697 = 31527716
139 + 31527577 = 31527716
193 + 31527523 = 31527716
373 + 31527343 = 31527716
439 + 31527277 = 31527716
463 + 31527253 = 31527716

Showing the first eight; more decompositions exist.
