Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047428, here are decompositions:

37 + 1047391 = 1047428
61 + 1047367 = 1047428
139 + 1047289 = 1047428
157 + 1047271 = 1047428
181 + 1047247 = 1047428
199 + 1047229 = 1047428
229 + 1047199 = 1047428
271 + 1047157 = 1047428

Showing the first eight; more decompositions exist.
