Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489626, here are decompositions:

13 + 31489613 = 31489626
107 + 31489519 = 31489626
137 + 31489489 = 31489626
163 + 31489463 = 31489626
193 + 31489433 = 31489626
199 + 31489427 = 31489626
227 + 31489399 = 31489626
263 + 31489363 = 31489626

Showing the first eight; more decompositions exist.
