Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761788, here are decompositions:

37 + 8761751 = 8761788
67 + 8761721 = 8761788
97 + 8761691 = 8761788
149 + 8761639 = 8761788
157 + 8761631 = 8761788
241 + 8761547 = 8761788
251 + 8761537 = 8761788
257 + 8761531 = 8761788

Showing the first eight; more decompositions exist.
