Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447054, here are decompositions:

11 + 31447043 = 31447054
53 + 31447001 = 31447054
71 + 31446983 = 31447054
101 + 31446953 = 31447054
137 + 31446917 = 31447054
293 + 31446761 = 31447054
311 + 31446743 = 31447054
461 + 31446593 = 31447054

Showing the first eight; more decompositions exist.
