Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750090, here are decompositions:

43 + 8750047 = 8750090
73 + 8750017 = 8750090
79 + 8750011 = 8750090
109 + 8749981 = 8750090
163 + 8749927 = 8750090
199 + 8749891 = 8750090
277 + 8749813 = 8750090
337 + 8749753 = 8750090

Showing the first eight; more decompositions exist.
