Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473386, here are decompositions:

73 + 31473313 = 31473386
103 + 31473283 = 31473386
199 + 31473187 = 31473386
223 + 31473163 = 31473386
277 + 31473109 = 31473386
349 + 31473037 = 31473386
457 + 31472929 = 31473386
499 + 31472887 = 31473386

Showing the first eight; more decompositions exist.
