Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761844, here are decompositions:

37 + 8761807 = 8761844
211 + 8761633 = 8761844
307 + 8761537 = 8761844
313 + 8761531 = 8761844
337 + 8761507 = 8761844
541 + 8761303 = 8761844
547 + 8761297 = 8761844
601 + 8761243 = 8761844

Showing the first eight; more decompositions exist.
