Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540232, here are decompositions:

19 + 31540213 = 31540232
43 + 31540189 = 31540232
109 + 31540123 = 31540232
223 + 31540009 = 31540232
331 + 31539901 = 31540232
571 + 31539661 = 31540232
709 + 31539523 = 31540232
733 + 31539499 = 31540232

Showing the first eight; more decompositions exist.
