Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523030, here are decompositions:

3 + 31523027 = 31523030
43 + 31522987 = 31523030
79 + 31522951 = 31523030
157 + 31522873 = 31523030
283 + 31522747 = 31523030
313 + 31522717 = 31523030
337 + 31522693 = 31523030
367 + 31522663 = 31523030

Showing the first eight; more decompositions exist.
