Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540054, here are decompositions:

23 + 31540031 = 31540054
41 + 31540013 = 31540054
47 + 31540007 = 31540054
83 + 31539971 = 31540054
191 + 31539863 = 31540054
197 + 31539857 = 31540054
233 + 31539821 = 31540054
317 + 31539737 = 31540054

Showing the first eight; more decompositions exist.
