Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449946, here are decompositions:

23 + 31449923 = 31449946
179 + 31449767 = 31449946
257 + 31449689 = 31449946
317 + 31449629 = 31449946
389 + 31449557 = 31449946
419 + 31449527 = 31449946
467 + 31449479 = 31449946
569 + 31449377 = 31449946

Showing the first eight; more decompositions exist.
