Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473876, here are decompositions:

13 + 31473863 = 31473876
29 + 31473847 = 31473876
37 + 31473839 = 31473876
67 + 31473809 = 31473876
97 + 31473779 = 31473876
173 + 31473703 = 31473876
277 + 31473599 = 31473876
283 + 31473593 = 31473876

Showing the first eight; more decompositions exist.
