Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469782, here are decompositions:

41 + 31469741 = 31469782
59 + 31469723 = 31469782
251 + 31469531 = 31469782
263 + 31469519 = 31469782
269 + 31469513 = 31469782
359 + 31469423 = 31469782
479 + 31469303 = 31469782
503 + 31469279 = 31469782

Showing the first eight; more decompositions exist.
