Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541354, here are decompositions:

7 + 31541347 = 31541354
73 + 31541281 = 31541354
181 + 31541173 = 31541354
193 + 31541161 = 31541354
241 + 31541113 = 31541354
283 + 31541071 = 31541354
307 + 31541047 = 31541354
337 + 31541017 = 31541354

Showing the first eight; more decompositions exist.
