Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541294, here are decompositions:

13 + 31541281 = 31541294
61 + 31541233 = 31541294
181 + 31541113 = 31541294
193 + 31541101 = 31541294
223 + 31541071 = 31541294
277 + 31541017 = 31541294
373 + 31540921 = 31541294
457 + 31540837 = 31541294

Showing the first eight; more decompositions exist.
