Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562752, here are decompositions:

41 + 31562711 = 31562752
131 + 31562621 = 31562752
149 + 31562603 = 31562752
233 + 31562519 = 31562752
251 + 31562501 = 31562752
269 + 31562483 = 31562752
311 + 31562441 = 31562752
461 + 31562291 = 31562752

Showing the first eight; more decompositions exist.
