Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744158, here are decompositions:

29 + 8744129 = 8744158
167 + 8743991 = 8744158
239 + 8743919 = 8744158
257 + 8743901 = 8744158
389 + 8743769 = 8744158
569 + 8743589 = 8744158
587 + 8743571 = 8744158
659 + 8743499 = 8744158

Showing the first eight; more decompositions exist.
