Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040558, here are decompositions:

37 + 1040521 = 1040558
109 + 1040449 = 1040558
139 + 1040419 = 1040558
151 + 1040407 = 1040558
331 + 1040227 = 1040558
367 + 1040191 = 1040558
397 + 1040161 = 1040558
439 + 1040119 = 1040558

Showing the first eight; more decompositions exist.
