Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541284, here are decompositions:

3 + 31541281 = 31541284
17 + 31541267 = 31541284
41 + 31541243 = 31541284
167 + 31541117 = 31541284
233 + 31541051 = 31541284
263 + 31541021 = 31541284
293 + 31540991 = 31541284
461 + 31540823 = 31541284

Showing the first eight; more decompositions exist.
