Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748404, here are decompositions:

37 + 8748367 = 8748404
43 + 8748361 = 8748404
73 + 8748331 = 8748404
127 + 8748277 = 8748404
307 + 8748097 = 8748404
373 + 8748031 = 8748404
433 + 8747971 = 8748404
463 + 8747941 = 8748404

Showing the first eight; more decompositions exist.
