Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731400, here are decompositions:

19 + 8731381 = 8731400
31 + 8731369 = 8731400
37 + 8731363 = 8731400
61 + 8731339 = 8731400
79 + 8731321 = 8731400
151 + 8731249 = 8731400
199 + 8731201 = 8731400
331 + 8731069 = 8731400

Showing the first eight; more decompositions exist.
