Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472752, here are decompositions:

29 + 31472723 = 31472752
53 + 31472699 = 31472752
83 + 31472669 = 31472752
89 + 31472663 = 31472752
251 + 31472501 = 31472752
263 + 31472489 = 31472752
401 + 31472351 = 31472752
461 + 31472291 = 31472752

Showing the first eight; more decompositions exist.
