Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540354, here are decompositions:

11 + 31540343 = 31540354
113 + 31540241 = 31540354
137 + 31540217 = 31540354
173 + 31540181 = 31540354
191 + 31540163 = 31540354
347 + 31540007 = 31540354
383 + 31539971 = 31540354
491 + 31539863 = 31540354

Showing the first eight; more decompositions exist.
