Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731892, here are decompositions:

19 + 8731873 = 8731892
31 + 8731861 = 8731892
61 + 8731831 = 8731892
73 + 8731819 = 8731892
109 + 8731783 = 8731892
181 + 8731711 = 8731892
193 + 8731699 = 8731892
283 + 8731609 = 8731892

Showing the first eight; more decompositions exist.
