Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541926, here are decompositions:

23 + 31541903 = 31541926
233 + 31541693 = 31541926
293 + 31541633 = 31541926
419 + 31541507 = 31541926
443 + 31541483 = 31541926
509 + 31541417 = 31541926
659 + 31541267 = 31541926
683 + 31541243 = 31541926

Showing the first eight; more decompositions exist.
