Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731670, here are decompositions:

43 + 8731627 = 8731670
61 + 8731609 = 8731670
139 + 8731531 = 8731670
193 + 8731477 = 8731670
223 + 8731447 = 8731670
307 + 8731363 = 8731670
331 + 8731339 = 8731670
349 + 8731321 = 8731670

Showing the first eight; more decompositions exist.
