Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641132, here are decompositions:

53 + 8641079 = 8641132
419 + 8640713 = 8641132
431 + 8640701 = 8641132
443 + 8640689 = 8641132
449 + 8640683 = 8641132
881 + 8640251 = 8641132
911 + 8640221 = 8641132
971 + 8640161 = 8641132

Showing the first eight; more decompositions exist.
