Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752780, here are decompositions:

11 + 8752769 = 8752780
83 + 8752697 = 8752780
137 + 8752643 = 8752780
167 + 8752613 = 8752780
227 + 8752553 = 8752780
269 + 8752511 = 8752780
353 + 8752427 = 8752780
359 + 8752421 = 8752780

Showing the first eight; more decompositions exist.
