Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745242, here are decompositions:

3 + 8745239 = 8745242
19 + 8745223 = 8745242
43 + 8745199 = 8745242
73 + 8745169 = 8745242
109 + 8745133 = 8745242
211 + 8745031 = 8745242
223 + 8745019 = 8745242
313 + 8744929 = 8745242

Showing the first eight; more decompositions exist.
