Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755442, here are decompositions:

43 + 8755399 = 8755442
61 + 8755381 = 8755442
103 + 8755339 = 8755442
151 + 8755291 = 8755442
211 + 8755231 = 8755442
379 + 8755063 = 8755442
463 + 8754979 = 8755442
523 + 8754919 = 8755442

Showing the first eight; more decompositions exist.
