Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722582, here are decompositions:

41 + 8722541 = 8722582
83 + 8722499 = 8722582
173 + 8722409 = 8722582
191 + 8722391 = 8722582
251 + 8722331 = 8722582
359 + 8722223 = 8722582
389 + 8722193 = 8722582
503 + 8722079 = 8722582

Showing the first eight; more decompositions exist.
