Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523070, here are decompositions:

17 + 31523053 = 31523070
43 + 31523027 = 31523070
67 + 31523003 = 31523070
83 + 31522987 = 31523070
109 + 31522961 = 31523070
181 + 31522889 = 31523070
197 + 31522873 = 31523070
223 + 31522847 = 31523070

Showing the first eight; more decompositions exist.
