Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489174, here are decompositions:

5 + 31489169 = 31489174
83 + 31489091 = 31489174
131 + 31489043 = 31489174
137 + 31489037 = 31489174
257 + 31488917 = 31489174
263 + 31488911 = 31489174
347 + 31488827 = 31489174
617 + 31488557 = 31489174

Showing the first eight; more decompositions exist.
