Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027642, here are decompositions:

29 + 1027613 = 1027642
149 + 1027493 = 1027642
233 + 1027409 = 1027642
251 + 1027391 = 1027642
311 + 1027331 = 1027642
353 + 1027289 = 1027642
401 + 1027241 = 1027642
419 + 1027223 = 1027642

Showing the first eight; more decompositions exist.
