Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522006, here are decompositions:

29 + 31521977 = 31522006
53 + 31521953 = 31522006
293 + 31521713 = 31522006
359 + 31521647 = 31522006
557 + 31521449 = 31522006
587 + 31521419 = 31522006
647 + 31521359 = 31522006
653 + 31521353 = 31522006

Showing the first eight; more decompositions exist.
