Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479502, here are decompositions:

3 + 31479499 = 31479502
11 + 31479491 = 31479502
83 + 31479419 = 31479502
233 + 31479269 = 31479502
251 + 31479251 = 31479502
401 + 31479101 = 31479502
419 + 31479083 = 31479502
569 + 31478933 = 31479502

Showing the first eight; more decompositions exist.
