Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547922, here are decompositions:

5 + 31547917 = 31547922
61 + 31547861 = 31547922
71 + 31547851 = 31547922
73 + 31547849 = 31547922
83 + 31547839 = 31547922
89 + 31547833 = 31547922
139 + 31547783 = 31547922
173 + 31547749 = 31547922

Showing the first eight; more decompositions exist.
