Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523066, here are decompositions:

13 + 31523053 = 31523066
79 + 31522987 = 31523066
193 + 31522873 = 31523066
349 + 31522717 = 31523066
373 + 31522693 = 31523066
397 + 31522669 = 31523066
409 + 31522657 = 31523066
433 + 31522633 = 31523066

Showing the first eight; more decompositions exist.
