Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479832, here are decompositions:

3 + 31479829 = 31479832
11 + 31479821 = 31479832
29 + 31479803 = 31479832
89 + 31479743 = 31479832
113 + 31479719 = 31479832
239 + 31479593 = 31479832
281 + 31479551 = 31479832
563 + 31479269 = 31479832

Showing the first eight; more decompositions exist.
