Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447050, here are decompositions:

7 + 31447043 = 31447050
23 + 31447027 = 31447050
29 + 31447021 = 31447050
31 + 31447019 = 31447050
53 + 31446997 = 31447050
67 + 31446983 = 31447050
97 + 31446953 = 31447050
101 + 31446949 = 31447050

Showing the first eight; more decompositions exist.
