Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616572, here are decompositions:

31 + 8616541 = 8616572
73 + 8616499 = 8616572
79 + 8616493 = 8616572
193 + 8616379 = 8616572
199 + 8616373 = 8616572
331 + 8616241 = 8616572
373 + 8616199 = 8616572
421 + 8616151 = 8616572

Showing the first eight; more decompositions exist.
