Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743928, here are decompositions:

157 + 8743771 = 8743928
181 + 8743747 = 8743928
211 + 8743717 = 8743928
307 + 8743621 = 8743928
331 + 8743597 = 8743928
367 + 8743561 = 8743928
379 + 8743549 = 8743928
397 + 8743531 = 8743928

Showing the first eight; more decompositions exist.
