Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452, here are decompositions:

59 + 31393 = 31452
61 + 31391 = 31452
73 + 31379 = 31452
131 + 31321 = 31452
181 + 31271 = 31452
193 + 31259 = 31452
199 + 31253 = 31452
229 + 31223 = 31452

Showing the first eight; more decompositions exist.
