Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489882, here are decompositions:

3 + 31489879 = 31489882
41 + 31489841 = 31489882
131 + 31489751 = 31489882
173 + 31489709 = 31489882
269 + 31489613 = 31489882
311 + 31489571 = 31489882
419 + 31489463 = 31489882
449 + 31489433 = 31489882

Showing the first eight; more decompositions exist.
