Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742722, here are decompositions:

151 + 8742571 = 8742722
181 + 8742541 = 8742722
193 + 8742529 = 8742722
211 + 8742511 = 8742722
223 + 8742499 = 8742722
229 + 8742493 = 8742722
409 + 8742313 = 8742722
463 + 8742259 = 8742722

Showing the first eight; more decompositions exist.
