Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488326, here are decompositions:

3 + 31488323 = 31488326
193 + 31488133 = 31488326
307 + 31488019 = 31488326
313 + 31488013 = 31488326
349 + 31487977 = 31488326
409 + 31487917 = 31488326
523 + 31487803 = 31488326
547 + 31487779 = 31488326

Showing the first eight; more decompositions exist.
