Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479844, here are decompositions:

23 + 31479821 = 31479844
41 + 31479803 = 31479844
101 + 31479743 = 31479844
107 + 31479737 = 31479844
173 + 31479671 = 31479844
197 + 31479647 = 31479844
251 + 31479593 = 31479844
293 + 31479551 = 31479844

Showing the first eight; more decompositions exist.
