Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562722, here are decompositions:

11 + 31562711 = 31562722
101 + 31562621 = 31562722
179 + 31562543 = 31562722
239 + 31562483 = 31562722
281 + 31562441 = 31562722
293 + 31562429 = 31562722
431 + 31562291 = 31562722
449 + 31562273 = 31562722

Showing the first eight; more decompositions exist.
