Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474958, here are decompositions:

157 + 31474801 = 31474958
181 + 31474777 = 31474958
211 + 31474747 = 31474958
271 + 31474687 = 31474958
409 + 31474549 = 31474958
439 + 31474519 = 31474958
457 + 31474501 = 31474958
601 + 31474357 = 31474958

Showing the first eight; more decompositions exist.
