Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488410, here are decompositions:

3 + 31488407 = 31488410
139 + 31488271 = 31488410
199 + 31488211 = 31488410
277 + 31488133 = 31488410
379 + 31488031 = 31488410
397 + 31488013 = 31488410
433 + 31487977 = 31488410
607 + 31487803 = 31488410

Showing the first eight; more decompositions exist.
