Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761838, here are decompositions:

31 + 8761807 = 8761838
199 + 8761639 = 8761838
307 + 8761531 = 8761838
331 + 8761507 = 8761838
409 + 8761429 = 8761838
499 + 8761339 = 8761838
541 + 8761297 = 8761838
601 + 8761237 = 8761838

Showing the first eight; more decompositions exist.
