Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722084, here are decompositions:

3 + 8722081 = 8722084
5 + 8722079 = 8722084
83 + 8722001 = 8722084
167 + 8721917 = 8722084
233 + 8721851 = 8722084
311 + 8721773 = 8722084
347 + 8721737 = 8722084
383 + 8721701 = 8722084

Showing the first eight; more decompositions exist.
