Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489584, here are decompositions:

13 + 31489571 = 31489584
43 + 31489541 = 31489584
151 + 31489433 = 31489584
157 + 31489427 = 31489584
167 + 31489417 = 31489584
173 + 31489411 = 31489584
193 + 31489391 = 31489584
337 + 31489247 = 31489584

Showing the first eight; more decompositions exist.
