Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552794, here are decompositions:

47 + 31552747 = 31552794
61 + 31552733 = 31552794
67 + 31552727 = 31552794
73 + 31552721 = 31552794
101 + 31552693 = 31552794
113 + 31552681 = 31552794
151 + 31552643 = 31552794
173 + 31552621 = 31552794

Showing the first eight; more decompositions exist.
