Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534156, here are decompositions:

53 + 31534103 = 31534156
83 + 31534073 = 31534156
89 + 31534067 = 31534156
197 + 31533959 = 31534156
233 + 31533923 = 31534156
317 + 31533839 = 31534156
383 + 31533773 = 31534156
449 + 31533707 = 31534156

Showing the first eight; more decompositions exist.
