Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047290, here are decompositions:

7 + 1047283 = 1047290
19 + 1047271 = 1047290
43 + 1047247 = 1047290
61 + 1047229 = 1047290
151 + 1047139 = 1047290
157 + 1047133 = 1047290
163 + 1047127 = 1047290
193 + 1047097 = 1047290

Showing the first eight; more decompositions exist.
