Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749130, here are decompositions:

3 + 8749127 = 8749130
43 + 8749087 = 8749130
139 + 8748991 = 8749130
151 + 8748979 = 8749130
157 + 8748973 = 8749130
241 + 8748889 = 8749130
277 + 8748853 = 8749130
283 + 8748847 = 8749130

Showing the first eight; more decompositions exist.
