Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732072, here are decompositions:

43 + 8732029 = 8732072
79 + 8731993 = 8732072
199 + 8731873 = 8732072
211 + 8731861 = 8732072
241 + 8731831 = 8732072
373 + 8731699 = 8732072
463 + 8731609 = 8732072
541 + 8731531 = 8732072

Showing the first eight; more decompositions exist.
