Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488014, here are decompositions:

37 + 31487977 = 31488014
73 + 31487941 = 31488014
97 + 31487917 = 31488014
211 + 31487803 = 31488014
367 + 31487647 = 31488014
373 + 31487641 = 31488014
433 + 31487581 = 31488014
463 + 31487551 = 31488014

Showing the first eight; more decompositions exist.
