Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552904, here are decompositions:

13 + 31552891 = 31552904
73 + 31552831 = 31552904
157 + 31552747 = 31552904
211 + 31552693 = 31552904
223 + 31552681 = 31552904
283 + 31552621 = 31552904
367 + 31552537 = 31552904
601 + 31552303 = 31552904

Showing the first eight; more decompositions exist.
