Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479326, here are decompositions:

19 + 31479307 = 31479326
37 + 31479289 = 31479326
199 + 31479127 = 31479326
367 + 31478959 = 31479326
607 + 31478719 = 31479326
727 + 31478599 = 31479326
733 + 31478593 = 31479326
937 + 31478389 = 31479326

Showing the first eight; more decompositions exist.
