Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454364, here are decompositions:

13 + 31454351 = 31454364
43 + 31454321 = 31454364
101 + 31454263 = 31454364
163 + 31454201 = 31454364
167 + 31454197 = 31454364
173 + 31454191 = 31454364
241 + 31454123 = 31454364
281 + 31454083 = 31454364

Showing the first eight; more decompositions exist.
