Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446236, here are decompositions:

7 + 31446229 = 31446236
13 + 31446223 = 31446236
103 + 31446133 = 31446236
139 + 31446097 = 31446236
277 + 31445959 = 31446236
307 + 31445929 = 31446236
373 + 31445863 = 31446236
883 + 31445353 = 31446236

Showing the first eight; more decompositions exist.
