Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743742, here are decompositions:

31 + 8743711 = 8743742
61 + 8743681 = 8743742
103 + 8743639 = 8743742
109 + 8743633 = 8743742
181 + 8743561 = 8743742
193 + 8743549 = 8743742
211 + 8743531 = 8743742
229 + 8743513 = 8743742

Showing the first eight; more decompositions exist.
