Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541288, here are decompositions:

7 + 31541281 = 31541288
19 + 31541269 = 31541288
109 + 31541179 = 31541288
127 + 31541161 = 31541288
241 + 31541047 = 31541288
271 + 31541017 = 31541288
349 + 31540939 = 31541288
367 + 31540921 = 31541288

Showing the first eight; more decompositions exist.
