Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722150, here are decompositions:

53 + 8722097 = 8722150
71 + 8722079 = 8722150
131 + 8722019 = 8722150
149 + 8722001 = 8722150
233 + 8721917 = 8722150
401 + 8721749 = 8722150
449 + 8721701 = 8722150
617 + 8721533 = 8722150

Showing the first eight; more decompositions exist.
