Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473682, here are decompositions:

83 + 31473599 = 31473682
89 + 31473593 = 31473682
101 + 31473581 = 31473682
269 + 31473413 = 31473682
419 + 31473263 = 31473682
431 + 31473251 = 31473682
479 + 31473203 = 31473682
491 + 31473191 = 31473682

Showing the first eight; more decompositions exist.
