Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031158, here are decompositions:

17 + 1031141 = 1031158
41 + 1031117 = 1031158
101 + 1031057 = 1031158
239 + 1030919 = 1031158
269 + 1030889 = 1031158
311 + 1030847 = 1031158
347 + 1030811 = 1031158
419 + 1030739 = 1031158

Showing the first eight; more decompositions exist.
