Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534358, here are decompositions:

61 + 31534297 = 31534358
127 + 31534231 = 31534358
241 + 31534117 = 31534358
307 + 31534051 = 31534358
379 + 31533979 = 31534358
409 + 31533949 = 31534358
439 + 31533919 = 31534358
487 + 31533871 = 31534358

Showing the first eight; more decompositions exist.
