Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562074, here are decompositions:

17 + 31562057 = 31562074
41 + 31562033 = 31562074
101 + 31561973 = 31562074
107 + 31561967 = 31562074
227 + 31561847 = 31562074
251 + 31561823 = 31562074
263 + 31561811 = 31562074
293 + 31561781 = 31562074

Showing the first eight; more decompositions exist.
