Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580062, here are decompositions:

5 + 31580057 = 31580062
11 + 31580051 = 31580062
53 + 31580009 = 31580062
149 + 31579913 = 31580062
359 + 31579703 = 31580062
401 + 31579661 = 31580062
419 + 31579643 = 31580062
443 + 31579619 = 31580062

Showing the first eight; more decompositions exist.
