Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455060, here are decompositions:

19 + 31455041 = 31455060
29 + 31455031 = 31455060
61 + 31454999 = 31455060
89 + 31454971 = 31455060
103 + 31454957 = 31455060
107 + 31454953 = 31455060
137 + 31454923 = 31455060
151 + 31454909 = 31455060

Showing the first eight; more decompositions exist.
