Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477450, here are decompositions:

3 + 31477447 = 31477450
23 + 31477427 = 31477450
71 + 31477379 = 31477450
101 + 31477349 = 31477450
149 + 31477301 = 31477450
269 + 31477181 = 31477450
383 + 31477067 = 31477450
491 + 31476959 = 31477450

Showing the first eight; more decompositions exist.
