Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744790, here are decompositions:

53 + 8744737 = 8744790
73 + 8744717 = 8744790
79 + 8744711 = 8744790
83 + 8744707 = 8744790
107 + 8744683 = 8744790
127 + 8744663 = 8744790
163 + 8744627 = 8744790
179 + 8744611 = 8744790

Showing the first eight; more decompositions exist.
