Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446744, here are decompositions:

5 + 31446739 = 31446744
103 + 31446641 = 31446744
137 + 31446607 = 31446744
151 + 31446593 = 31446744
181 + 31446563 = 31446744
191 + 31446553 = 31446744
211 + 31446533 = 31446744
283 + 31446461 = 31446744

Showing the first eight; more decompositions exist.
