Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622284, here are decompositions:

3 + 31622281 = 31622284
11 + 31622273 = 31622284
47 + 31622237 = 31622284
101 + 31622183 = 31622284
131 + 31622153 = 31622284
137 + 31622147 = 31622284
383 + 31621901 = 31622284
647 + 31621637 = 31622284

Showing the first eight; more decompositions exist.
