Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761490, here are decompositions:

37 + 8761453 = 8761490
61 + 8761429 = 8761490
151 + 8761339 = 8761490
163 + 8761327 = 8761490
193 + 8761297 = 8761490
211 + 8761279 = 8761490
277 + 8761213 = 8761490
313 + 8761177 = 8761490

Showing the first eight; more decompositions exist.
