Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449774, here are decompositions:

7 + 31449767 = 31449774
17 + 31449757 = 31449774
23 + 31449751 = 31449774
73 + 31449701 = 31449774
101 + 31449673 = 31449774
127 + 31449647 = 31449774
137 + 31449637 = 31449774
163 + 31449611 = 31449774

Showing the first eight; more decompositions exist.
