Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047286, here are decompositions:

3 + 1047283 = 1047286
5 + 1047281 = 1047286
47 + 1047239 = 1047286
89 + 1047197 = 1047286
113 + 1047173 = 1047286
167 + 1047119 = 1047286
179 + 1047107 = 1047286
197 + 1047089 = 1047286

Showing the first eight; more decompositions exist.
