Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055042, here are decompositions:

3 + 1055039 = 1055042
139 + 1054903 = 1055042
199 + 1054843 = 1055042
211 + 1054831 = 1055042
223 + 1054819 = 1055042
229 + 1054813 = 1055042
421 + 1054621 = 1055042
433 + 1054609 = 1055042

Showing the first eight; more decompositions exist.
