Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562246, here are decompositions:

3 + 31562243 = 31562246
109 + 31562137 = 31562246
127 + 31562119 = 31562246
139 + 31562107 = 31562246
193 + 31562053 = 31562246
223 + 31562023 = 31562246
229 + 31562017 = 31562246
277 + 31561969 = 31562246

Showing the first eight; more decompositions exist.
