Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579846, here are decompositions:

83 + 31579763 = 31579846
107 + 31579739 = 31579846
227 + 31579619 = 31579846
503 + 31579343 = 31579846
569 + 31579277 = 31579846
653 + 31579193 = 31579846
659 + 31579187 = 31579846
719 + 31579127 = 31579846

Showing the first eight; more decompositions exist.
