Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611994, here are decompositions:

3 + 8611991 = 8611994
7 + 8611987 = 8611994
103 + 8611891 = 8611994
211 + 8611783 = 8611994
271 + 8611723 = 8611994
331 + 8611663 = 8611994
397 + 8611597 = 8611994
421 + 8611573 = 8611994

Showing the first eight; more decompositions exist.
