Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464452, here are decompositions:

13 + 31464439 = 31464452
31 + 31464421 = 31464452
43 + 31464409 = 31464452
181 + 31464271 = 31464452
373 + 31464079 = 31464452
421 + 31464031 = 31464452
541 + 31463911 = 31464452
673 + 31463779 = 31464452

Showing the first eight; more decompositions exist.
