Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532102, here are decompositions:

13 + 31532089 = 31532102
31 + 31532071 = 31532102
181 + 31531921 = 31532102
193 + 31531909 = 31532102
463 + 31531639 = 31532102
523 + 31531579 = 31532102
619 + 31531483 = 31532102
631 + 31531471 = 31532102

Showing the first eight; more decompositions exist.
