Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541408, here are decompositions:

7 + 31541401 = 31541408
61 + 31541347 = 31541408
127 + 31541281 = 31541408
139 + 31541269 = 31541408
229 + 31541179 = 31541408
307 + 31541101 = 31541408
337 + 31541071 = 31541408
487 + 31540921 = 31541408

Showing the first eight; more decompositions exist.
