Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743830, here are decompositions:

13 + 8743817 = 8743830
23 + 8743807 = 8743830
59 + 8743771 = 8743830
61 + 8743769 = 8743830
83 + 8743747 = 8743830
97 + 8743733 = 8743830
113 + 8743717 = 8743830
149 + 8743681 = 8743830

Showing the first eight; more decompositions exist.
