Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031290, here are decompositions:

11 + 1031279 = 1031290
23 + 1031267 = 1031290
59 + 1031231 = 1031290
101 + 1031189 = 1031290
149 + 1031141 = 1031290
173 + 1031117 = 1031290
233 + 1031057 = 1031290
401 + 1030889 = 1031290

Showing the first eight; more decompositions exist.
