Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8694642, here are decompositions:

29 + 8694613 = 8694642
101 + 8694541 = 8694642
163 + 8694479 = 8694642
191 + 8694451 = 8694642
193 + 8694449 = 8694642
263 + 8694379 = 8694642
311 + 8694331 = 8694642
401 + 8694241 = 8694642

Showing the first eight; more decompositions exist.
