Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473510, here are decompositions:

23 + 31473487 = 31473510
31 + 31473479 = 31473510
53 + 31473457 = 31473510
73 + 31473437 = 31473510
97 + 31473413 = 31473510
113 + 31473397 = 31473510
151 + 31473359 = 31473510
179 + 31473331 = 31473510

Showing the first eight; more decompositions exist.
