Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651378, here are decompositions:

19 + 8651359 = 8651378
67 + 8651311 = 8651378
97 + 8651281 = 8651378
139 + 8651239 = 8651378
199 + 8651179 = 8651378
331 + 8651047 = 8651378
397 + 8650981 = 8651378
499 + 8650879 = 8651378

Showing the first eight; more decompositions exist.
