Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462406, here are decompositions:

43 + 31462363 = 31462406
67 + 31462339 = 31462406
139 + 31462267 = 31462406
337 + 31462069 = 31462406
457 + 31461949 = 31462406
463 + 31461943 = 31462406
487 + 31461919 = 31462406
643 + 31461763 = 31462406

Showing the first eight; more decompositions exist.
