Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527722, here are decompositions:

13 + 31527709 = 31527722
19 + 31527703 = 31527722
139 + 31527583 = 31527722
181 + 31527541 = 31527722
199 + 31527523 = 31527722
223 + 31527499 = 31527722
241 + 31527481 = 31527722
379 + 31527343 = 31527722

Showing the first eight; more decompositions exist.
