Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672406, here are decompositions:

19 + 8672387 = 8672406
53 + 8672353 = 8672406
59 + 8672347 = 8672406
73 + 8672333 = 8672406
109 + 8672297 = 8672406
139 + 8672267 = 8672406
167 + 8672239 = 8672406
199 + 8672207 = 8672406

Showing the first eight; more decompositions exist.
