Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579676, here are decompositions:

43 + 31579633 = 31579676
109 + 31579567 = 31579676
157 + 31579519 = 31579676
199 + 31579477 = 31579676
223 + 31579453 = 31579676
229 + 31579447 = 31579676
277 + 31579399 = 31579676
283 + 31579393 = 31579676

Showing the first eight; more decompositions exist.
