Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057388, here are decompositions:

97 + 1057291 = 1057388
109 + 1057279 = 1057388
139 + 1057249 = 1057388
151 + 1057237 = 1057388
271 + 1057117 = 1057388
337 + 1057051 = 1057388
439 + 1056949 = 1057388
811 + 1056577 = 1057388

Showing the first eight; more decompositions exist.
