Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055538, here are decompositions:

7 + 1055531 = 1055538
37 + 1055501 = 1055538
67 + 1055471 = 1055538
101 + 1055437 = 1055538
109 + 1055429 = 1055538
131 + 1055407 = 1055538
139 + 1055399 = 1055538
151 + 1055387 = 1055538

Showing the first eight; more decompositions exist.
