Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461384, here are decompositions:

23 + 31461361 = 31461384
41 + 31461343 = 31461384
43 + 31461341 = 31461384
83 + 31461301 = 31461384
103 + 31461281 = 31461384
131 + 31461253 = 31461384
191 + 31461193 = 31461384
193 + 31461191 = 31461384

Showing the first eight; more decompositions exist.
