Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447534, here are decompositions:

5 + 31447529 = 31447534
47 + 31447487 = 31447534
233 + 31447301 = 31447534
281 + 31447253 = 31447534
317 + 31447217 = 31447534
353 + 31447181 = 31447534
401 + 31447133 = 31447534
431 + 31447103 = 31447534

Showing the first eight; more decompositions exist.
