Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488584, here are decompositions:

37 + 31488547 = 31488584
103 + 31488481 = 31488584
151 + 31488433 = 31488584
313 + 31488271 = 31488584
373 + 31488211 = 31488584
571 + 31488013 = 31488584
607 + 31487977 = 31488584
643 + 31487941 = 31488584

Showing the first eight; more decompositions exist.
