Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541076, here are decompositions:

5 + 31541071 = 31541076
29 + 31541047 = 31541076
37 + 31541039 = 31541076
59 + 31541017 = 31541076
97 + 31540979 = 31541076
137 + 31540939 = 31541076
239 + 31540837 = 31541076
263 + 31540813 = 31541076

Showing the first eight; more decompositions exist.
