Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464300, here are decompositions:

19 + 31464281 = 31464300
29 + 31464271 = 31464300
31 + 31464269 = 31464300
67 + 31464233 = 31464300
107 + 31464193 = 31464300
113 + 31464187 = 31464300
151 + 31464149 = 31464300
157 + 31464143 = 31464300

Showing the first eight; more decompositions exist.
