Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731874, here are decompositions:

7 + 8731867 = 8731874
13 + 8731861 = 8731874
43 + 8731831 = 8731874
97 + 8731777 = 8731874
163 + 8731711 = 8731874
373 + 8731501 = 8731874
397 + 8731477 = 8731874
457 + 8731417 = 8731874

Showing the first eight; more decompositions exist.
