Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534394, here are decompositions:

61 + 31534333 = 31534394
97 + 31534297 = 31534394
163 + 31534231 = 31534394
211 + 31534183 = 31534394
277 + 31534117 = 31534394
337 + 31534057 = 31534394
523 + 31533871 = 31534394
547 + 31533847 = 31534394

Showing the first eight; more decompositions exist.
