Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743486, here are decompositions:

107 + 8743379 = 8743486
137 + 8743349 = 8743486
317 + 8743169 = 8743486
347 + 8743139 = 8743486
383 + 8743103 = 8743486
419 + 8743067 = 8743486
443 + 8743043 = 8743486
449 + 8743037 = 8743486

Showing the first eight; more decompositions exist.
