Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744742, here are decompositions:

5 + 8744737 = 8744742
31 + 8744711 = 8744742
59 + 8744683 = 8744742
79 + 8744663 = 8744742
131 + 8744611 = 8744742
179 + 8744563 = 8744742
191 + 8744551 = 8744742
229 + 8744513 = 8744742

Showing the first eight; more decompositions exist.
