Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749178, here are decompositions:

37 + 8749141 = 8749178
199 + 8748979 = 8749178
331 + 8748847 = 8749178
337 + 8748841 = 8749178
367 + 8748811 = 8749178
439 + 8748739 = 8749178
577 + 8748601 = 8749178
709 + 8748469 = 8749178

Showing the first eight; more decompositions exist.
