Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8753780, here are decompositions:

37 + 8753743 = 8753780
67 + 8753713 = 8753780
73 + 8753707 = 8753780
193 + 8753587 = 8753780
199 + 8753581 = 8753780
223 + 8753557 = 8753780
241 + 8753539 = 8753780
331 + 8753449 = 8753780

Showing the first eight; more decompositions exist.
