Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473608, here are decompositions:

79 + 31473529 = 31473608
151 + 31473457 = 31473608
211 + 31473397 = 31473608
277 + 31473331 = 31473608
367 + 31473241 = 31473608
421 + 31473187 = 31473608
457 + 31473151 = 31473608
499 + 31473109 = 31473608

Showing the first eight; more decompositions exist.
