Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488502, here are decompositions:

5 + 31488497 = 31488502
131 + 31488371 = 31488502
173 + 31488329 = 31488502
179 + 31488323 = 31488502
401 + 31488101 = 31488502
431 + 31488071 = 31488502
443 + 31488059 = 31488502
449 + 31488053 = 31488502

Showing the first eight; more decompositions exist.
