Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630378, here are decompositions:

67 + 8630311 = 8630378
109 + 8630269 = 8630378
139 + 8630239 = 8630378
199 + 8630179 = 8630378
307 + 8630071 = 8630378
349 + 8630029 = 8630378
397 + 8629981 = 8630378
487 + 8629891 = 8630378

Showing the first eight; more decompositions exist.
