Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464476, here are decompositions:

13 + 31464463 = 31464476
37 + 31464439 = 31464476
67 + 31464409 = 31464476
79 + 31464397 = 31464476
283 + 31464193 = 31464476
397 + 31464079 = 31464476
409 + 31464067 = 31464476
619 + 31463857 = 31464476

Showing the first eight; more decompositions exist.
