Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722412, here are decompositions:

3 + 8722409 = 8722412
19 + 8722393 = 8722412
73 + 8722339 = 8722412
79 + 8722333 = 8722412
109 + 8722303 = 8722412
241 + 8722171 = 8722412
313 + 8722099 = 8722412
331 + 8722081 = 8722412

Showing the first eight; more decompositions exist.
