Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628452, here are decompositions:

3 + 8628449 = 8628452
31 + 8628421 = 8628452
103 + 8628349 = 8628452
181 + 8628271 = 8628452
271 + 8628181 = 8628452
331 + 8628121 = 8628452
421 + 8628031 = 8628452
433 + 8628019 = 8628452

Showing the first eight; more decompositions exist.
