Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756144, here are decompositions:

31 + 8756113 = 8756144
37 + 8756107 = 8756144
43 + 8756101 = 8756144
181 + 8755963 = 8756144
193 + 8755951 = 8756144
223 + 8755921 = 8756144
421 + 8755723 = 8756144
433 + 8755711 = 8756144

Showing the first eight; more decompositions exist.
