Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462360, here are decompositions:

3 + 31462357 = 31462360
11 + 31462349 = 31462360
47 + 31462313 = 31462360
71 + 31462289 = 31462360
227 + 31462133 = 31462360
233 + 31462127 = 31462360
257 + 31462103 = 31462360
353 + 31462007 = 31462360

Showing the first eight; more decompositions exist.
