Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454504, here are decompositions:

7 + 31454497 = 31454504
43 + 31454461 = 31454504
73 + 31454431 = 31454504
127 + 31454377 = 31454504
241 + 31454263 = 31454504
283 + 31454221 = 31454504
307 + 31454197 = 31454504
313 + 31454191 = 31454504

Showing the first eight; more decompositions exist.
