Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681622, here are decompositions:

43 + 8681579 = 8681622
73 + 8681549 = 8681622
83 + 8681539 = 8681622
109 + 8681513 = 8681622
139 + 8681483 = 8681622
149 + 8681473 = 8681622
193 + 8681429 = 8681622
263 + 8681359 = 8681622

Showing the first eight; more decompositions exist.
