Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544046, here are decompositions:

5 + 31544041 = 31544046
7 + 31544039 = 31544046
13 + 31544033 = 31544046
59 + 31543987 = 31544046
67 + 31543979 = 31544046
139 + 31543907 = 31544046
173 + 31543873 = 31544046
199 + 31543847 = 31544046

Showing the first eight; more decompositions exist.
