Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749330, here are decompositions:

101 + 8749229 = 8749330
131 + 8749199 = 8749330
167 + 8749163 = 8749330
179 + 8749151 = 8749330
197 + 8749133 = 8749330
281 + 8749049 = 8749330
311 + 8749019 = 8749330
449 + 8748881 = 8749330

Showing the first eight; more decompositions exist.
