Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547850, here are decompositions:

11 + 31547839 = 31547850
13 + 31547837 = 31547850
17 + 31547833 = 31547850
67 + 31547783 = 31547850
101 + 31547749 = 31547850
149 + 31547701 = 31547850
157 + 31547693 = 31547850
167 + 31547683 = 31547850

Showing the first eight; more decompositions exist.
