Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525246, here are decompositions:

3 + 31525243 = 31525246
17 + 31525229 = 31525246
83 + 31525163 = 31525246
239 + 31525007 = 31525246
257 + 31524989 = 31525246
353 + 31524893 = 31525246
383 + 31524863 = 31525246
449 + 31524797 = 31525246

Showing the first eight; more decompositions exist.
