Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562184, here are decompositions:

47 + 31562137 = 31562184
67 + 31562117 = 31562184
127 + 31562057 = 31562184
131 + 31562053 = 31562184
151 + 31562033 = 31562184
167 + 31562017 = 31562184
191 + 31561993 = 31562184
211 + 31561973 = 31562184

Showing the first eight; more decompositions exist.
