Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031378, here are decompositions:

31 + 1031347 = 1031378
79 + 1031299 = 1031378
97 + 1031281 = 1031378
241 + 1031137 = 1031378
331 + 1031047 = 1031378
421 + 1030957 = 1031378
547 + 1030831 = 1031378
577 + 1030801 = 1031378

Showing the first eight; more decompositions exist.
