Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743402, here are decompositions:

23 + 8743379 = 8743402
53 + 8743349 = 8743402
71 + 8743331 = 8743402
233 + 8743169 = 8743402
263 + 8743139 = 8743402
281 + 8743121 = 8743402
359 + 8743043 = 8743402
383 + 8743019 = 8743402

Showing the first eight; more decompositions exist.
