Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582070, here are decompositions:

43 + 31582027 = 31582070
67 + 31582003 = 31582070
73 + 31581997 = 31582070
97 + 31581973 = 31582070
109 + 31581961 = 31582070
181 + 31581889 = 31582070
193 + 31581877 = 31582070
211 + 31581859 = 31582070

Showing the first eight; more decompositions exist.
