Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749740, here are decompositions:

7 + 8749733 = 8749740
71 + 8749669 = 8749740
89 + 8749651 = 8749740
113 + 8749627 = 8749740
127 + 8749613 = 8749740
137 + 8749603 = 8749740
151 + 8749589 = 8749740
191 + 8749549 = 8749740

Showing the first eight; more decompositions exist.
