Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638412, here are decompositions:

31 + 8638381 = 8638412
73 + 8638339 = 8638412
193 + 8638219 = 8638412
199 + 8638213 = 8638412
229 + 8638183 = 8638412
373 + 8638039 = 8638412
379 + 8638033 = 8638412
421 + 8637991 = 8638412

Showing the first eight; more decompositions exist.
