Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747450, here are decompositions:

31 + 8747419 = 8747450
43 + 8747407 = 8747450
193 + 8747257 = 8747450
199 + 8747251 = 8747450
331 + 8747119 = 8747450
367 + 8747083 = 8747450
379 + 8747071 = 8747450
409 + 8747041 = 8747450

Showing the first eight; more decompositions exist.
