Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534546, here are decompositions:

3 + 31534543 = 31534546
53 + 31534493 = 31534546
59 + 31534487 = 31534546
89 + 31534457 = 31534546
347 + 31534199 = 31534546
359 + 31534187 = 31534546
443 + 31534103 = 31534546
467 + 31534079 = 31534546

Showing the first eight; more decompositions exist.
