Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488054, here are decompositions:

23 + 31488031 = 31488054
41 + 31488013 = 31488054
61 + 31487993 = 31488054
97 + 31487957 = 31488054
113 + 31487941 = 31488054
137 + 31487917 = 31488054
181 + 31487873 = 31488054
251 + 31487803 = 31488054

Showing the first eight; more decompositions exist.
