Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489846, here are decompositions:

5 + 31489841 = 31489846
29 + 31489817 = 31489846
137 + 31489709 = 31489846
173 + 31489673 = 31489846
233 + 31489613 = 31489846
383 + 31489463 = 31489846
419 + 31489427 = 31489846
587 + 31489259 = 31489846

Showing the first eight; more decompositions exist.
