Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525152, here are decompositions:

31 + 31525121 = 31525152
163 + 31524989 = 31525152
313 + 31524839 = 31525152
359 + 31524793 = 31525152
389 + 31524763 = 31525152
431 + 31524721 = 31525152
479 + 31524673 = 31525152
509 + 31524643 = 31525152

Showing the first eight; more decompositions exist.
