Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749260, here are decompositions:

17 + 8749243 = 8749260
31 + 8749229 = 8749260
41 + 8749219 = 8749260
53 + 8749207 = 8749260
61 + 8749199 = 8749260
97 + 8749163 = 8749260
109 + 8749151 = 8749260
127 + 8749133 = 8749260

Showing the first eight; more decompositions exist.
