Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672636, here are decompositions:

73 + 8672563 = 8672636
97 + 8672539 = 8672636
109 + 8672527 = 8672636
127 + 8672509 = 8672636
229 + 8672407 = 8672636
283 + 8672353 = 8672636
373 + 8672263 = 8672636
397 + 8672239 = 8672636

Showing the first eight; more decompositions exist.
