Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488152, here are decompositions:

19 + 31488133 = 31488152
43 + 31488109 = 31488152
61 + 31488091 = 31488152
139 + 31488013 = 31488152
211 + 31487941 = 31488152
349 + 31487803 = 31488152
373 + 31487779 = 31488152
571 + 31487581 = 31488152

Showing the first eight; more decompositions exist.
