Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541116, here are decompositions:

3 + 31541113 = 31541116
137 + 31540979 = 31541116
293 + 31540823 = 31541116
389 + 31540727 = 31541116
479 + 31540637 = 31541116
587 + 31540529 = 31541116
617 + 31540499 = 31541116
773 + 31540343 = 31541116

Showing the first eight; more decompositions exist.
