Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540052, here are decompositions:

43 + 31540009 = 31540052
151 + 31539901 = 31540052
163 + 31539889 = 31540052
409 + 31539643 = 31540052
613 + 31539439 = 31540052
631 + 31539421 = 31540052
769 + 31539283 = 31540052
811 + 31539241 = 31540052

Showing the first eight; more decompositions exist.
