Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447354, here are decompositions:

53 + 31447301 = 31447354
101 + 31447253 = 31447354
137 + 31447217 = 31447354
173 + 31447181 = 31447354
251 + 31447103 = 31447354
311 + 31447043 = 31447354
353 + 31447001 = 31447354
401 + 31446953 = 31447354

Showing the first eight; more decompositions exist.
