Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541450, here are decompositions:

13 + 31541437 = 31541450
103 + 31541347 = 31541450
181 + 31541269 = 31541450
271 + 31541179 = 31541450
277 + 31541173 = 31541450
337 + 31541113 = 31541450
349 + 31541101 = 31541450
379 + 31541071 = 31541450

Showing the first eight; more decompositions exist.
