Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761508, here are decompositions:

79 + 8761429 = 8761508
181 + 8761327 = 8761508
211 + 8761297 = 8761508
229 + 8761279 = 8761508
271 + 8761237 = 8761508
331 + 8761177 = 8761508
367 + 8761141 = 8761508
409 + 8761099 = 8761508

Showing the first eight; more decompositions exist.
