Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055158, here are decompositions:

17 + 1055141 = 1055158
101 + 1055057 = 1055158
227 + 1054931 = 1055158
389 + 1054769 = 1055158
479 + 1054679 = 1055158
491 + 1054667 = 1055158
509 + 1054649 = 1055158
641 + 1054517 = 1055158

Showing the first eight; more decompositions exist.
