Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534162, here are decompositions:

41 + 31534121 = 31534162
59 + 31534103 = 31534162
83 + 31534079 = 31534162
89 + 31534073 = 31534162
239 + 31533923 = 31534162
251 + 31533911 = 31534162
389 + 31533773 = 31534162
503 + 31533659 = 31534162

Showing the first eight; more decompositions exist.
