Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464392, here are decompositions:

199 + 31464193 = 31464392
313 + 31464079 = 31464392
331 + 31464061 = 31464392
433 + 31463959 = 31464392
499 + 31463893 = 31464392
613 + 31463779 = 31464392
859 + 31463533 = 31464392
1039 + 31463353 = 31464392

Showing the first eight; more decompositions exist.
