Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743340, here are decompositions:

13 + 8743327 = 8743340
31 + 8743309 = 8743340
61 + 8743279 = 8743340
79 + 8743261 = 8743340
127 + 8743213 = 8743340
241 + 8743099 = 8743340
313 + 8743027 = 8743340
367 + 8742973 = 8743340

Showing the first eight; more decompositions exist.
