Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506054, here are decompositions:

23 + 31506031 = 31506054
61 + 31505993 = 31506054
71 + 31505983 = 31506054
127 + 31505927 = 31506054
131 + 31505923 = 31506054
211 + 31505843 = 31506054
233 + 31505821 = 31506054
241 + 31505813 = 31506054

Showing the first eight; more decompositions exist.
