Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626462, here are decompositions:

41 + 31626421 = 31626462
73 + 31626389 = 31626462
79 + 31626383 = 31626462
103 + 31626359 = 31626462
139 + 31626323 = 31626462
229 + 31626233 = 31626462
233 + 31626229 = 31626462
269 + 31626193 = 31626462

Showing the first eight; more decompositions exist.
