Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758212, here are decompositions:

11 + 8758201 = 8758212
13 + 8758199 = 8758212
41 + 8758171 = 8758212
83 + 8758129 = 8758212
109 + 8758103 = 8758212
131 + 8758081 = 8758212
163 + 8758049 = 8758212
251 + 8757961 = 8758212

Showing the first eight; more decompositions exist.
