Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473686, here are decompositions:

103 + 31473583 = 31473686
157 + 31473529 = 31473686
163 + 31473523 = 31473686
199 + 31473487 = 31473686
229 + 31473457 = 31473686
373 + 31473313 = 31473686
499 + 31473187 = 31473686
523 + 31473163 = 31473686

Showing the first eight; more decompositions exist.
