Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574674, here are decompositions:

3 + 31574671 = 31574674
17 + 31574657 = 31574674
167 + 31574507 = 31574674
311 + 31574363 = 31574674
347 + 31574327 = 31574674
653 + 31574021 = 31574674
743 + 31573931 = 31574674
821 + 31573853 = 31574674

Showing the first eight; more decompositions exist.
