Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474928, here are decompositions:

61 + 31474867 = 31474928
127 + 31474801 = 31474928
151 + 31474777 = 31474928
181 + 31474747 = 31474928
241 + 31474687 = 31474928
379 + 31474549 = 31474928
409 + 31474519 = 31474928
439 + 31474489 = 31474928

Showing the first eight; more decompositions exist.
