Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562058, here are decompositions:

5 + 31562053 = 31562058
41 + 31562017 = 31562058
89 + 31561969 = 31562058
131 + 31561927 = 31562058
139 + 31561919 = 31562058
211 + 31561847 = 31562058
251 + 31561807 = 31562058
257 + 31561801 = 31562058

Showing the first eight; more decompositions exist.
