Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579734, here are decompositions:

13 + 31579721 = 31579734
31 + 31579703 = 31579734
73 + 31579661 = 31579734
83 + 31579651 = 31579734
101 + 31579633 = 31579734
167 + 31579567 = 31579734
191 + 31579543 = 31579734
223 + 31579511 = 31579734

Showing the first eight; more decompositions exist.
