Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464402, here are decompositions:

5 + 31464397 = 31464402
43 + 31464359 = 31464402
61 + 31464341 = 31464402
131 + 31464271 = 31464402
401 + 31464001 = 31464402
439 + 31463963 = 31464402
443 + 31463959 = 31464402
461 + 31463941 = 31464402

Showing the first eight; more decompositions exist.
