Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704820, here are decompositions:

37 + 8704783 = 8704820
43 + 8704777 = 8704820
97 + 8704723 = 8704820
109 + 8704711 = 8704820
199 + 8704621 = 8704820
211 + 8704609 = 8704820
307 + 8704513 = 8704820
541 + 8704279 = 8704820

Showing the first eight; more decompositions exist.
