Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731700, here are decompositions:

13 + 8731687 = 8731700
73 + 8731627 = 8731700
199 + 8731501 = 8731700
223 + 8731477 = 8731700
283 + 8731417 = 8731700
331 + 8731369 = 8731700
337 + 8731363 = 8731700
379 + 8731321 = 8731700

Showing the first eight; more decompositions exist.
