Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731742, here are decompositions:

31 + 8731711 = 8731742
43 + 8731699 = 8731742
163 + 8731579 = 8731742
211 + 8731531 = 8731742
241 + 8731501 = 8731742
373 + 8731369 = 8731742
379 + 8731363 = 8731742
421 + 8731321 = 8731742

Showing the first eight; more decompositions exist.
