Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761540, here are decompositions:

3 + 8761537 = 8761540
23 + 8761517 = 8761540
71 + 8761469 = 8761540
83 + 8761457 = 8761540
101 + 8761439 = 8761540
107 + 8761433 = 8761540
251 + 8761289 = 8761540
383 + 8761157 = 8761540

Showing the first eight; more decompositions exist.
