Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540204, here are decompositions:

23 + 31540181 = 31540204
41 + 31540163 = 31540204
173 + 31540031 = 31540204
191 + 31540013 = 31540204
197 + 31540007 = 31540204
233 + 31539971 = 31540204
347 + 31539857 = 31540204
383 + 31539821 = 31540204

Showing the first eight; more decompositions exist.
