Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562210, here are decompositions:

73 + 31562137 = 31562210
103 + 31562107 = 31562210
157 + 31562053 = 31562210
193 + 31562017 = 31562210
241 + 31561969 = 31562210
271 + 31561939 = 31562210
283 + 31561927 = 31562210
307 + 31561903 = 31562210

Showing the first eight; more decompositions exist.
