Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527392, here are decompositions:

3 + 31527389 = 31527392
139 + 31527253 = 31527392
181 + 31527211 = 31527392
199 + 31527193 = 31527392
241 + 31527151 = 31527392
283 + 31527109 = 31527392
439 + 31526953 = 31527392
499 + 31526893 = 31527392

Showing the first eight; more decompositions exist.
