Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446936, here are decompositions:

19 + 31446917 = 31446936
43 + 31446893 = 31446936
83 + 31446853 = 31446936
89 + 31446847 = 31446936
97 + 31446839 = 31446936
167 + 31446769 = 31446936
179 + 31446757 = 31446936
193 + 31446743 = 31446936

Showing the first eight; more decompositions exist.
