Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489434, here are decompositions:

7 + 31489427 = 31489434
17 + 31489417 = 31489434
23 + 31489411 = 31489434
43 + 31489391 = 31489434
71 + 31489363 = 31489434
191 + 31489243 = 31489434
241 + 31489193 = 31489434
257 + 31489177 = 31489434

Showing the first eight; more decompositions exist.
