Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621632, here are decompositions:

23 + 8621609 = 8621632
179 + 8621453 = 8621632
293 + 8621339 = 8621632
389 + 8621243 = 8621632
419 + 8621213 = 8621632
431 + 8621201 = 8621632
443 + 8621189 = 8621632
449 + 8621183 = 8621632

Showing the first eight; more decompositions exist.
