Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627426, here are decompositions:

53 + 31627373 = 31627426
107 + 31627319 = 31627426
137 + 31627289 = 31627426
179 + 31627247 = 31627426
293 + 31627133 = 31627426
353 + 31627073 = 31627426
419 + 31627007 = 31627426
449 + 31626977 = 31627426

Showing the first eight; more decompositions exist.
