Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756072, here are decompositions:

109 + 8755963 = 8756072
151 + 8755921 = 8756072
181 + 8755891 = 8756072
223 + 8755849 = 8756072
331 + 8755741 = 8756072
349 + 8755723 = 8756072
373 + 8755699 = 8756072
433 + 8755639 = 8756072

Showing the first eight; more decompositions exist.
