Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562196, here are decompositions:

59 + 31562137 = 31562196
79 + 31562117 = 31562196
89 + 31562107 = 31562196
97 + 31562099 = 31562196
103 + 31562093 = 31562196
139 + 31562057 = 31562196
163 + 31562033 = 31562196
173 + 31562023 = 31562196

Showing the first eight; more decompositions exist.
