Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552852, here are decompositions:

5 + 31552847 = 31552852
131 + 31552721 = 31552852
263 + 31552589 = 31552852
431 + 31552421 = 31552852
449 + 31552403 = 31552852
599 + 31552253 = 31552852
641 + 31552211 = 31552852
659 + 31552193 = 31552852

Showing the first eight; more decompositions exist.
