Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618132, here are decompositions:

13 + 8618119 = 8618132
43 + 8618089 = 8618132
73 + 8618059 = 8618132
139 + 8617993 = 8618132
199 + 8617933 = 8618132
379 + 8617753 = 8618132
433 + 8617699 = 8618132
571 + 8617561 = 8618132

Showing the first eight; more decompositions exist.
