Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477452, here are decompositions:

5 + 31477447 = 31477452
23 + 31477429 = 31477452
29 + 31477423 = 31477452
53 + 31477399 = 31477452
73 + 31477379 = 31477452
101 + 31477351 = 31477452
103 + 31477349 = 31477452
131 + 31477321 = 31477452

Showing the first eight; more decompositions exist.
