Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671148, here are decompositions:

97 + 8671051 = 8671148
139 + 8671009 = 8671148
151 + 8670997 = 8671148
229 + 8670919 = 8671148
337 + 8670811 = 8671148
397 + 8670751 = 8671148
439 + 8670709 = 8671148
751 + 8670397 = 8671148

Showing the first eight; more decompositions exist.
