Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031450, here are decompositions:

3 + 1031447 = 1031450
19 + 1031431 = 1031450
37 + 1031413 = 1031450
103 + 1031347 = 1031450
127 + 1031323 = 1031450
151 + 1031299 = 1031450
313 + 1031137 = 1031450
331 + 1031119 = 1031450

Showing the first eight; more decompositions exist.
