Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743720, here are decompositions:

3 + 8743717 = 8743720
47 + 8743673 = 8743720
131 + 8743589 = 8743720
137 + 8743583 = 8743720
149 + 8743571 = 8743720
173 + 8743547 = 8743720
311 + 8743409 = 8743720
353 + 8743367 = 8743720

Showing the first eight; more decompositions exist.
