Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738574, here are decompositions:

7 + 8738567 = 8738574
41 + 8738533 = 8738574
67 + 8738507 = 8738574
83 + 8738491 = 8738574
101 + 8738473 = 8738574
127 + 8738447 = 8738574
137 + 8738437 = 8738574
167 + 8738407 = 8738574

Showing the first eight; more decompositions exist.
