Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482394, here are decompositions:

5 + 31482389 = 31482394
101 + 31482293 = 31482394
113 + 31482281 = 31482394
137 + 31482257 = 31482394
227 + 31482167 = 31482394
311 + 31482083 = 31482394
347 + 31482047 = 31482394
353 + 31482041 = 31482394

Showing the first eight; more decompositions exist.
