Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021258, here are decompositions:

5 + 1021253 = 1021258
41 + 1021217 = 1021258
59 + 1021199 = 1021258
101 + 1021157 = 1021258
131 + 1021127 = 1021258
167 + 1021091 = 1021258
191 + 1021067 = 1021258
239 + 1021019 = 1021258

Showing the first eight; more decompositions exist.
