Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552754, here are decompositions:

7 + 31552747 = 31552754
61 + 31552693 = 31552754
73 + 31552681 = 31552754
151 + 31552603 = 31552754
367 + 31552387 = 31552754
547 + 31552207 = 31552754
757 + 31551997 = 31552754
853 + 31551901 = 31552754

Showing the first eight; more decompositions exist.
