Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525222, here are decompositions:

11 + 31525211 = 31525222
59 + 31525163 = 31525222
101 + 31525121 = 31525222
191 + 31525031 = 31525222
233 + 31524989 = 31525222
359 + 31524863 = 31525222
383 + 31524839 = 31525222
431 + 31524791 = 31525222

Showing the first eight; more decompositions exist.
