Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462436, here are decompositions:

3 + 31462433 = 31462436
73 + 31462363 = 31462436
79 + 31462357 = 31462436
97 + 31462339 = 31462436
163 + 31462273 = 31462436
367 + 31462069 = 31462436
433 + 31462003 = 31462436
457 + 31461979 = 31462436

Showing the first eight; more decompositions exist.
