Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540082, here are decompositions:

19 + 31540063 = 31540082
73 + 31540009 = 31540082
151 + 31539931 = 31540082
181 + 31539901 = 31540082
193 + 31539889 = 31540082
421 + 31539661 = 31540082
433 + 31539649 = 31540082
439 + 31539643 = 31540082

Showing the first eight; more decompositions exist.
