Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534462, here are decompositions:

5 + 31534457 = 31534462
191 + 31534271 = 31534462
263 + 31534199 = 31534462
293 + 31534169 = 31534462
359 + 31534103 = 31534462
383 + 31534079 = 31534462
389 + 31534073 = 31534462
503 + 31533959 = 31534462

Showing the first eight; more decompositions exist.
