Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449502, here are decompositions:

3 + 31449499 = 31449502
23 + 31449479 = 31449502
53 + 31449449 = 31449502
101 + 31449401 = 31449502
179 + 31449323 = 31449502
239 + 31449263 = 31449502
269 + 31449233 = 31449502
311 + 31449191 = 31449502

Showing the first eight; more decompositions exist.
