Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636402, here are decompositions:

13 + 8636389 = 8636402
139 + 8636263 = 8636402
163 + 8636239 = 8636402
421 + 8635981 = 8636402
433 + 8635969 = 8636402
673 + 8635729 = 8636402
739 + 8635663 = 8636402
823 + 8635579 = 8636402

Showing the first eight; more decompositions exist.
