Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482292, here are decompositions:

11 + 31482281 = 31482292
113 + 31482179 = 31482292
173 + 31482119 = 31482292
251 + 31482041 = 31482292
311 + 31481981 = 31482292
353 + 31481939 = 31482292
449 + 31481843 = 31482292
461 + 31481831 = 31482292

Showing the first eight; more decompositions exist.
