Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606126, here are decompositions:

29 + 31606097 = 31606126
47 + 31606079 = 31606126
59 + 31606067 = 31606126
173 + 31605953 = 31606126
197 + 31605929 = 31606126
317 + 31605809 = 31606126
347 + 31605779 = 31606126
353 + 31605773 = 31606126

Showing the first eight; more decompositions exist.
