Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473886, here are decompositions:

23 + 31473863 = 31473886
47 + 31473839 = 31473886
107 + 31473779 = 31473886
179 + 31473707 = 31473886
293 + 31473593 = 31473886
449 + 31473437 = 31473886
677 + 31473209 = 31473886
683 + 31473203 = 31473886

Showing the first eight; more decompositions exist.
