Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731868, here are decompositions:

7 + 8731861 = 8731868
37 + 8731831 = 8731868
157 + 8731711 = 8731868
181 + 8731687 = 8731868
241 + 8731627 = 8731868
337 + 8731531 = 8731868
367 + 8731501 = 8731868
421 + 8731447 = 8731868

Showing the first eight; more decompositions exist.
