Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485452, here are decompositions:

3 + 31485449 = 31485452
73 + 31485379 = 31485452
139 + 31485313 = 31485452
151 + 31485301 = 31485452
331 + 31485121 = 31485452
373 + 31485079 = 31485452
421 + 31485031 = 31485452
433 + 31485019 = 31485452

Showing the first eight; more decompositions exist.
