Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731802, here are decompositions:

19 + 8731783 = 8731802
103 + 8731699 = 8731802
193 + 8731609 = 8731802
223 + 8731579 = 8731802
271 + 8731531 = 8731802
421 + 8731381 = 8731802
433 + 8731369 = 8731802
439 + 8731363 = 8731802

Showing the first eight; more decompositions exist.
