Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452262, here are decompositions:

29 + 31452233 = 31452262
53 + 31452209 = 31452262
59 + 31452203 = 31452262
89 + 31452173 = 31452262
131 + 31452131 = 31452262
173 + 31452089 = 31452262
263 + 31451999 = 31452262
269 + 31451993 = 31452262

Showing the first eight; more decompositions exist.
