Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576554, here are decompositions:

5 + 31576549 = 31576554
13 + 31576541 = 31576554
43 + 31576511 = 31576554
71 + 31576483 = 31576554
101 + 31576453 = 31576554
127 + 31576427 = 31576554
137 + 31576417 = 31576554
151 + 31576403 = 31576554

Showing the first eight; more decompositions exist.
