Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489574, here are decompositions:

3 + 31489571 = 31489574
157 + 31489417 = 31489574
163 + 31489411 = 31489574
211 + 31489363 = 31489574
331 + 31489243 = 31489574
397 + 31489177 = 31489574
547 + 31489027 = 31489574
643 + 31488931 = 31489574

Showing the first eight; more decompositions exist.
