Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743380, here are decompositions:

13 + 8743367 = 8743380
31 + 8743349 = 8743380
53 + 8743327 = 8743380
71 + 8743309 = 8743380
101 + 8743279 = 8743380
103 + 8743277 = 8743380
167 + 8743213 = 8743380
211 + 8743169 = 8743380

Showing the first eight; more decompositions exist.
