Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455482, here are decompositions:

73 + 31455409 = 31455482
181 + 31455301 = 31455482
211 + 31455271 = 31455482
379 + 31455103 = 31455482
601 + 31454881 = 31455482
673 + 31454809 = 31455482
829 + 31454653 = 31455482
1021 + 31454461 = 31455482

Showing the first eight; more decompositions exist.
