Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488482, here are decompositions:

13 + 31488469 = 31488482
19 + 31488463 = 31488482
211 + 31488271 = 31488482
271 + 31488211 = 31488482
349 + 31488133 = 31488482
373 + 31488109 = 31488482
463 + 31488019 = 31488482
541 + 31487941 = 31488482

Showing the first eight; more decompositions exist.
