Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462574, here are decompositions:

43 + 31462531 = 31462574
67 + 31462507 = 31462574
103 + 31462471 = 31462574
193 + 31462381 = 31462574
211 + 31462363 = 31462574
223 + 31462351 = 31462574
307 + 31462267 = 31462574
433 + 31462141 = 31462574

Showing the first eight; more decompositions exist.
