Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562098, here are decompositions:

5 + 31562093 = 31562098
41 + 31562057 = 31562098
89 + 31562009 = 31562098
131 + 31561967 = 31562098
179 + 31561919 = 31562098
251 + 31561847 = 31562098
317 + 31561781 = 31562098
401 + 31561697 = 31562098

Showing the first eight; more decompositions exist.
