Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749184, here are decompositions:

43 + 8749141 = 8749184
97 + 8749087 = 8749184
193 + 8748991 = 8749184
211 + 8748973 = 8749184
307 + 8748877 = 8749184
331 + 8748853 = 8749184
337 + 8748847 = 8749184
373 + 8748811 = 8749184

Showing the first eight; more decompositions exist.
