Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464200, here are decompositions:

7 + 31464193 = 31464200
13 + 31464187 = 31464200
139 + 31464061 = 31464200
199 + 31464001 = 31464200
241 + 31463959 = 31464200
307 + 31463893 = 31464200
373 + 31463827 = 31464200
421 + 31463779 = 31464200

Showing the first eight; more decompositions exist.
