Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722312, here are decompositions:

29 + 8722283 = 8722312
89 + 8722223 = 8722312
101 + 8722211 = 8722312
233 + 8722079 = 8722312
293 + 8722019 = 8722312
311 + 8722001 = 8722312
383 + 8721929 = 8722312
461 + 8721851 = 8722312

Showing the first eight; more decompositions exist.
