Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552724, here are decompositions:

3 + 31552721 = 31552724
31 + 31552693 = 31552724
43 + 31552681 = 31552724
103 + 31552621 = 31552724
331 + 31552393 = 31552724
337 + 31552387 = 31552724
373 + 31552351 = 31552724
421 + 31552303 = 31552724

Showing the first eight; more decompositions exist.
