Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749148, here are decompositions:

7 + 8749141 = 8749148
61 + 8749087 = 8749148
157 + 8748991 = 8749148
271 + 8748877 = 8749148
307 + 8748841 = 8749148
337 + 8748811 = 8749148
409 + 8748739 = 8749148
439 + 8748709 = 8749148

Showing the first eight; more decompositions exist.
