Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637854, here are decompositions:

7 + 8637847 = 8637854
67 + 8637787 = 8637854
157 + 8637697 = 8637854
331 + 8637523 = 8637854
373 + 8637481 = 8637854
601 + 8637253 = 8637854
607 + 8637247 = 8637854
691 + 8637163 = 8637854

Showing the first eight; more decompositions exist.
