Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619572, here are decompositions:

61 + 8619511 = 8619572
103 + 8619469 = 8619572
139 + 8619433 = 8619572
151 + 8619421 = 8619572
229 + 8619343 = 8619572
331 + 8619241 = 8619572
349 + 8619223 = 8619572
373 + 8619199 = 8619572

Showing the first eight; more decompositions exist.
