Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576262, here are decompositions:

31 + 31576231 = 31576262
43 + 31576219 = 31576262
61 + 31576201 = 31576262
271 + 31575991 = 31576262
433 + 31575829 = 31576262
439 + 31575823 = 31576262
463 + 31575799 = 31576262
691 + 31575571 = 31576262

Showing the first eight; more decompositions exist.
