Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479826, here are decompositions:

5 + 31479821 = 31479826
23 + 31479803 = 31479826
83 + 31479743 = 31479826
89 + 31479737 = 31479826
107 + 31479719 = 31479826
179 + 31479647 = 31479826
233 + 31479593 = 31479826
269 + 31479557 = 31479826

Showing the first eight; more decompositions exist.
