Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541964, here are decompositions:

31 + 31541933 = 31541964
61 + 31541903 = 31541964
71 + 31541893 = 31541964
73 + 31541891 = 31541964
107 + 31541857 = 31541964
137 + 31541827 = 31541964
227 + 31541737 = 31541964
257 + 31541707 = 31541964

Showing the first eight; more decompositions exist.
