Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534138, here are decompositions:

17 + 31534121 = 31534138
59 + 31534079 = 31534138
71 + 31534067 = 31534138
179 + 31533959 = 31534138
227 + 31533911 = 31534138
347 + 31533791 = 31534138
431 + 31533707 = 31534138
479 + 31533659 = 31534138

Showing the first eight; more decompositions exist.
