Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527692, here are decompositions:

3 + 31527689 = 31527692
109 + 31527583 = 31527692
151 + 31527541 = 31527692
193 + 31527499 = 31527692
211 + 31527481 = 31527692
349 + 31527343 = 31527692
439 + 31527253 = 31527692
499 + 31527193 = 31527692

Showing the first eight; more decompositions exist.
