Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574752, here are decompositions:

5 + 31574747 = 31574752
29 + 31574723 = 31574752
59 + 31574693 = 31574752
71 + 31574681 = 31574752
113 + 31574639 = 31574752
263 + 31574489 = 31574752
383 + 31574369 = 31574752
389 + 31574363 = 31574752

Showing the first eight; more decompositions exist.
