Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541342, here are decompositions:

61 + 31541281 = 31541342
73 + 31541269 = 31541342
109 + 31541233 = 31541342
163 + 31541179 = 31541342
181 + 31541161 = 31541342
229 + 31541113 = 31541342
241 + 31541101 = 31541342
271 + 31541071 = 31541342

Showing the first eight; more decompositions exist.
