Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541296, here are decompositions:

29 + 31541267 = 31541296
53 + 31541243 = 31541296
167 + 31541129 = 31541296
179 + 31541117 = 31541296
257 + 31541039 = 31541296
317 + 31540979 = 31541296
509 + 31540787 = 31541296
569 + 31540727 = 31541296

Showing the first eight; more decompositions exist.
