Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449352, here are decompositions:

29 + 31449323 = 31449352
89 + 31449263 = 31449352
173 + 31449179 = 31449352
269 + 31449083 = 31449352
281 + 31449071 = 31449352
443 + 31448909 = 31449352
449 + 31448903 = 31449352
461 + 31448891 = 31449352

Showing the first eight; more decompositions exist.
