Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449412, here are decompositions:

3 + 31449409 = 31449412
11 + 31449401 = 31449412
53 + 31449359 = 31449412
89 + 31449323 = 31449412
149 + 31449263 = 31449412
179 + 31449233 = 31449412
233 + 31449179 = 31449412
359 + 31449053 = 31449412

Showing the first eight; more decompositions exist.
