Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541462, here are decompositions:

13 + 31541449 = 31541462
61 + 31541401 = 31541462
103 + 31541359 = 31541462
181 + 31541281 = 31541462
193 + 31541269 = 31541462
229 + 31541233 = 31541462
283 + 31541179 = 31541462
349 + 31541113 = 31541462

Showing the first eight; more decompositions exist.
