Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562050, here are decompositions:

17 + 31562033 = 31562050
41 + 31562009 = 31562050
83 + 31561967 = 31562050
131 + 31561919 = 31562050
227 + 31561823 = 31562050
239 + 31561811 = 31562050
269 + 31561781 = 31562050
353 + 31561697 = 31562050

Showing the first eight; more decompositions exist.
