Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552424, here are decompositions:

3 + 31552421 = 31552424
31 + 31552393 = 31552424
37 + 31552387 = 31552424
73 + 31552351 = 31552424
367 + 31552057 = 31552424
487 + 31551937 = 31552424
523 + 31551901 = 31552424
571 + 31551853 = 31552424

Showing the first eight; more decompositions exist.
