Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473518, here are decompositions:

31 + 31473487 = 31473518
61 + 31473457 = 31473518
277 + 31473241 = 31473518
331 + 31473187 = 31473518
367 + 31473151 = 31473518
409 + 31473109 = 31473518
457 + 31473061 = 31473518
487 + 31473031 = 31473518

Showing the first eight; more decompositions exist.
