Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454084, here are decompositions:

3 + 31454081 = 31454084
7 + 31454077 = 31454084
31 + 31454053 = 31454084
61 + 31454023 = 31454084
127 + 31453957 = 31454084
271 + 31453813 = 31454084
373 + 31453711 = 31454084
433 + 31453651 = 31454084

Showing the first eight; more decompositions exist.
