Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464410, here are decompositions:

13 + 31464397 = 31464410
139 + 31464271 = 31464410
223 + 31464187 = 31464410
331 + 31464079 = 31464410
349 + 31464061 = 31464410
379 + 31464031 = 31464410
409 + 31464001 = 31464410
499 + 31463911 = 31464410

Showing the first eight; more decompositions exist.
