Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469590, here are decompositions:

3 + 31469587 = 31469590
11 + 31469579 = 31469590
29 + 31469561 = 31469590
59 + 31469531 = 31469590
71 + 31469519 = 31469590
149 + 31469441 = 31469590
167 + 31469423 = 31469590
179 + 31469411 = 31469590

Showing the first eight; more decompositions exist.
