Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055290, here are decompositions:

23 + 1055267 = 1055290
29 + 1055261 = 1055290
59 + 1055231 = 1055290
101 + 1055189 = 1055290
149 + 1055141 = 1055290
227 + 1055063 = 1055290
233 + 1055057 = 1055290
251 + 1055039 = 1055290

Showing the first eight; more decompositions exist.
