Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609054, here are decompositions:

5 + 31609049 = 31609054
23 + 31609031 = 31609054
83 + 31608971 = 31609054
101 + 31608953 = 31609054
137 + 31608917 = 31609054
167 + 31608887 = 31609054
233 + 31608821 = 31609054
317 + 31608737 = 31609054

Showing the first eight; more decompositions exist.
