Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540482, here are decompositions:

11 + 31540471 = 31540482
41 + 31540441 = 31540482
139 + 31540343 = 31540482
173 + 31540309 = 31540482
241 + 31540241 = 31540482
269 + 31540213 = 31540482
271 + 31540211 = 31540482
293 + 31540189 = 31540482

Showing the first eight; more decompositions exist.
