Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472502, here are decompositions:

13 + 31472489 = 31472502
23 + 31472479 = 31472502
53 + 31472449 = 31472502
151 + 31472351 = 31472502
163 + 31472339 = 31472502
211 + 31472291 = 31472502
241 + 31472261 = 31472502
263 + 31472239 = 31472502

Showing the first eight; more decompositions exist.
