Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576418, here are decompositions:

7 + 31576411 = 31576418
67 + 31576351 = 31576418
151 + 31576267 = 31576418
157 + 31576261 = 31576418
199 + 31576219 = 31576418
331 + 31576087 = 31576418
409 + 31576009 = 31576418
541 + 31575877 = 31576418

Showing the first eight; more decompositions exist.
