Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562952, here are decompositions:

41 + 31562911 = 31562952
103 + 31562849 = 31562952
151 + 31562801 = 31562952
173 + 31562779 = 31562952
241 + 31562711 = 31562952
269 + 31562683 = 31562952
331 + 31562621 = 31562952
349 + 31562603 = 31562952

Showing the first eight; more decompositions exist.
