Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678722, here are decompositions:

23 + 8678699 = 8678722
29 + 8678693 = 8678722
53 + 8678669 = 8678722
83 + 8678639 = 8678722
359 + 8678363 = 8678722
383 + 8678339 = 8678722
389 + 8678333 = 8678722
509 + 8678213 = 8678722

Showing the first eight; more decompositions exist.
