Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541976, here are decompositions:

5 + 31541971 = 31541976
43 + 31541933 = 31541976
73 + 31541903 = 31541976
83 + 31541893 = 31541976
107 + 31541869 = 31541976
149 + 31541827 = 31541976
239 + 31541737 = 31541976
269 + 31541707 = 31541976

Showing the first eight; more decompositions exist.
