Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473846, here are decompositions:

7 + 31473839 = 31473846
37 + 31473809 = 31473846
67 + 31473779 = 31473846
113 + 31473733 = 31473846
139 + 31473707 = 31473846
263 + 31473583 = 31473846
317 + 31473529 = 31473846
359 + 31473487 = 31473846

Showing the first eight; more decompositions exist.
