Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748722, here are decompositions:

13 + 8748709 = 8748722
79 + 8748643 = 8748722
139 + 8748583 = 8748722
223 + 8748499 = 8748722
523 + 8748199 = 8748722
613 + 8748109 = 8748722
691 + 8748031 = 8748722
751 + 8747971 = 8748722

Showing the first eight; more decompositions exist.
