Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472476, here are decompositions:

137 + 31472339 = 31472476
293 + 31472183 = 31472476
317 + 31472159 = 31472476
353 + 31472123 = 31472476
509 + 31471967 = 31472476
569 + 31471907 = 31472476
593 + 31471883 = 31472476
653 + 31471823 = 31472476

Showing the first eight; more decompositions exist.
