Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636902, here are decompositions:

3 + 8636899 = 8636902
83 + 8636819 = 8636902
101 + 8636801 = 8636902
269 + 8636633 = 8636902
311 + 8636591 = 8636902
353 + 8636549 = 8636902
359 + 8636543 = 8636902
389 + 8636513 = 8636902

Showing the first eight; more decompositions exist.
