Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611940, here are decompositions:

37 + 8611903 = 8611940
61 + 8611879 = 8611940
67 + 8611873 = 8611940
151 + 8611789 = 8611940
157 + 8611783 = 8611940
277 + 8611663 = 8611940
307 + 8611633 = 8611940
367 + 8611573 = 8611940

Showing the first eight; more decompositions exist.
