Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541382, here are decompositions:

23 + 31541359 = 31541382
101 + 31541281 = 31541382
113 + 31541269 = 31541382
139 + 31541243 = 31541382
149 + 31541233 = 31541382
241 + 31541141 = 31541382
269 + 31541113 = 31541382
281 + 31541101 = 31541382

Showing the first eight; more decompositions exist.
