Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488962, here are decompositions:

3 + 31488959 = 31488962
31 + 31488931 = 31488962
103 + 31488859 = 31488962
163 + 31488799 = 31488962
229 + 31488733 = 31488962
331 + 31488631 = 31488962
499 + 31488463 = 31488962
691 + 31488271 = 31488962

Showing the first eight; more decompositions exist.
