Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031420, here are decompositions:

7 + 1031413 = 1031420
73 + 1031347 = 1031420
97 + 1031323 = 1031420
139 + 1031281 = 1031420
283 + 1031137 = 1031420
367 + 1031053 = 1031420
373 + 1031047 = 1031420
433 + 1030987 = 1031420

Showing the first eight; more decompositions exist.
