Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731748, here are decompositions:

37 + 8731711 = 8731748
61 + 8731687 = 8731748
139 + 8731609 = 8731748
271 + 8731477 = 8731748
331 + 8731417 = 8731748
367 + 8731381 = 8731748
379 + 8731369 = 8731748
409 + 8731339 = 8731748

Showing the first eight; more decompositions exist.
