Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534588, here are decompositions:

101 + 31534487 = 31534588
131 + 31534457 = 31534588
317 + 31534271 = 31534588
347 + 31534241 = 31534588
389 + 31534199 = 31534588
401 + 31534187 = 31534588
419 + 31534169 = 31534588
467 + 31534121 = 31534588

Showing the first eight; more decompositions exist.
