Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629208, here are decompositions:

37 + 8629171 = 8629208
67 + 8629141 = 8629208
199 + 8629009 = 8629208
241 + 8628967 = 8629208
271 + 8628937 = 8629208
349 + 8628859 = 8629208
397 + 8628811 = 8629208
409 + 8628799 = 8629208

Showing the first eight; more decompositions exist.
