Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479332, here are decompositions:

43 + 31479289 = 31479332
61 + 31479271 = 31479332
271 + 31479061 = 31479332
331 + 31479001 = 31479332
349 + 31478983 = 31479332
373 + 31478959 = 31479332
421 + 31478911 = 31479332
613 + 31478719 = 31479332

Showing the first eight; more decompositions exist.
