Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541086, here are decompositions:

47 + 31541039 = 31541086
107 + 31540979 = 31541086
263 + 31540823 = 31541086
359 + 31540727 = 31541086
443 + 31540643 = 31541086
449 + 31540637 = 31541086
557 + 31540529 = 31541086
587 + 31540499 = 31541086

Showing the first eight; more decompositions exist.
