Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722444, here are decompositions:

53 + 8722391 = 8722444
83 + 8722361 = 8722444
113 + 8722331 = 8722444
233 + 8722211 = 8722444
251 + 8722193 = 8722444
257 + 8722187 = 8722444
347 + 8722097 = 8722444
443 + 8722001 = 8722444

Showing the first eight; more decompositions exist.
