Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496070, here are decompositions:

13 + 31496057 = 31496070
29 + 31496041 = 31496070
43 + 31496027 = 31496070
59 + 31496011 = 31496070
149 + 31495921 = 31496070
173 + 31495897 = 31496070
191 + 31495879 = 31496070
211 + 31495859 = 31496070

Showing the first eight; more decompositions exist.
