Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667830, here are decompositions:

37 + 8667793 = 8667830
97 + 8667733 = 8667830
103 + 8667727 = 8667830
109 + 8667721 = 8667830
229 + 8667601 = 8667830
271 + 8667559 = 8667830
373 + 8667457 = 8667830
541 + 8667289 = 8667830

Showing the first eight; more decompositions exist.
