Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464428, here are decompositions:

7 + 31464421 = 31464428
19 + 31464409 = 31464428
31 + 31464397 = 31464428
157 + 31464271 = 31464428
241 + 31464187 = 31464428
349 + 31464079 = 31464428
367 + 31464061 = 31464428
397 + 31464031 = 31464428

Showing the first eight; more decompositions exist.
