Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449794, here are decompositions:

3 + 31449791 = 31449794
37 + 31449757 = 31449794
43 + 31449751 = 31449794
97 + 31449697 = 31449794
157 + 31449637 = 31449794
223 + 31449571 = 31449794
241 + 31449553 = 31449794
331 + 31449463 = 31449794

Showing the first eight; more decompositions exist.
