Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486252, here are decompositions:

23 + 31486229 = 31486252
89 + 31486163 = 31486252
131 + 31486121 = 31486252
293 + 31485959 = 31486252
311 + 31485941 = 31486252
359 + 31485893 = 31486252
419 + 31485833 = 31486252
449 + 31485803 = 31486252

Showing the first eight; more decompositions exist.
