Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453252, here are decompositions:

3 + 31453249 = 31453252
11 + 31453241 = 31453252
59 + 31453193 = 31453252
71 + 31453181 = 31453252
401 + 31452851 = 31453252
449 + 31452803 = 31453252
503 + 31452749 = 31453252
521 + 31452731 = 31453252

Showing the first eight; more decompositions exist.
