Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505452, here are decompositions:

5 + 31505447 = 31505452
71 + 31505381 = 31505452
131 + 31505321 = 31505452
149 + 31505303 = 31505452
239 + 31505213 = 31505452
263 + 31505189 = 31505452
269 + 31505183 = 31505452
311 + 31505141 = 31505452

Showing the first eight; more decompositions exist.
