Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541326, here are decompositions:

29 + 31541297 = 31541326
59 + 31541267 = 31541326
83 + 31541243 = 31541326
197 + 31541129 = 31541326
347 + 31540979 = 31541326
503 + 31540823 = 31541326
599 + 31540727 = 31541326
617 + 31540709 = 31541326

Showing the first eight; more decompositions exist.
