Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743418, here are decompositions:

7 + 8743411 = 8743418
109 + 8743309 = 8743418
139 + 8743279 = 8743418
157 + 8743261 = 8743418
331 + 8743087 = 8743418
421 + 8742997 = 8743418
487 + 8742931 = 8743418
499 + 8742919 = 8743418

Showing the first eight; more decompositions exist.
