Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636072, here are decompositions:

73 + 8635999 = 8636072
103 + 8635969 = 8636072
139 + 8635933 = 8636072
223 + 8635849 = 8636072
349 + 8635723 = 8636072
373 + 8635699 = 8636072
409 + 8635663 = 8636072
541 + 8635531 = 8636072

Showing the first eight; more decompositions exist.
