Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618906, here are decompositions:

13 + 8618893 = 8618906
73 + 8618833 = 8618906
97 + 8618809 = 8618906
157 + 8618749 = 8618906
223 + 8618683 = 8618906
313 + 8618593 = 8618906
349 + 8618557 = 8618906
463 + 8618443 = 8618906

Showing the first eight; more decompositions exist.
