Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479382, here are decompositions:

83 + 31479299 = 31479382
113 + 31479269 = 31479382
131 + 31479251 = 31479382
251 + 31479131 = 31479382
281 + 31479101 = 31479382
449 + 31478933 = 31479382
743 + 31478639 = 31479382
911 + 31478471 = 31479382

Showing the first eight; more decompositions exist.
