Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621282, here are decompositions:

73 + 8621209 = 8621282
139 + 8621143 = 8621282
181 + 8621101 = 8621282
193 + 8621089 = 8621282
199 + 8621083 = 8621282
331 + 8620951 = 8621282
409 + 8620873 = 8621282
421 + 8620861 = 8621282

Showing the first eight; more decompositions exist.
