Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8812, here are decompositions:

5 + 8807 = 8812
29 + 8783 = 8812
59 + 8753 = 8812
71 + 8741 = 8812
113 + 8699 = 8812
131 + 8681 = 8812
149 + 8663 = 8812
239 + 8573 = 8812

Showing the first eight; more decompositions exist.
