Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464368, here are decompositions:

97 + 31464271 = 31464368
181 + 31464187 = 31464368
307 + 31464061 = 31464368
337 + 31464031 = 31464368
367 + 31464001 = 31464368
409 + 31463959 = 31464368
457 + 31463911 = 31464368
541 + 31463827 = 31464368

Showing the first eight; more decompositions exist.
