Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464242, here are decompositions:

163 + 31464079 = 31464242
181 + 31464061 = 31464242
211 + 31464031 = 31464242
241 + 31464001 = 31464242
283 + 31463959 = 31464242
331 + 31463911 = 31464242
349 + 31463893 = 31464242
463 + 31463779 = 31464242

Showing the first eight; more decompositions exist.
