Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464438, here are decompositions:

11 + 31464427 = 31464438
17 + 31464421 = 31464438
29 + 31464409 = 31464438
37 + 31464401 = 31464438
41 + 31464397 = 31464438
79 + 31464359 = 31464438
97 + 31464341 = 31464438
157 + 31464281 = 31464438

Showing the first eight; more decompositions exist.
