Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621948, here are decompositions:

37 + 8621911 = 8621948
79 + 8621869 = 8621948
151 + 8621797 = 8621948
199 + 8621749 = 8621948
241 + 8621707 = 8621948
271 + 8621677 = 8621948
331 + 8621617 = 8621948
367 + 8621581 = 8621948

Showing the first eight; more decompositions exist.
