Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477502, here are decompositions:

19 + 31477483 = 31477502
73 + 31477429 = 31477502
79 + 31477423 = 31477502
103 + 31477399 = 31477502
151 + 31477351 = 31477502
181 + 31477321 = 31477502
211 + 31477291 = 31477502
439 + 31477063 = 31477502

Showing the first eight; more decompositions exist.
