Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481932, here are decompositions:

11 + 31481921 = 31481932
89 + 31481843 = 31481932
101 + 31481831 = 31481932
113 + 31481819 = 31481932
179 + 31481753 = 31481932
311 + 31481621 = 31481932
389 + 31481543 = 31481932
401 + 31481531 = 31481932

Showing the first eight; more decompositions exist.
