Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534126, here are decompositions:

5 + 31534121 = 31534126
23 + 31534103 = 31534126
47 + 31534079 = 31534126
53 + 31534073 = 31534126
59 + 31534067 = 31534126
167 + 31533959 = 31534126
293 + 31533833 = 31534126
353 + 31533773 = 31534126

Showing the first eight; more decompositions exist.
