Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051478, here are decompositions:

7 + 1051471 = 1051478
19 + 1051459 = 1051478
61 + 1051417 = 1051478
331 + 1051147 = 1051478
397 + 1051081 = 1051478
409 + 1051069 = 1051478
577 + 1050901 = 1051478
661 + 1050817 = 1051478

Showing the first eight; more decompositions exist.
