Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525498, here are decompositions:

101 + 31525397 = 31525498
131 + 31525367 = 31525498
167 + 31525331 = 31525498
269 + 31525229 = 31525498
461 + 31525037 = 31525498
467 + 31525031 = 31525498
491 + 31525007 = 31525498
509 + 31524989 = 31525498

Showing the first eight; more decompositions exist.
