Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576624, here are decompositions:

5 + 31576619 = 31576624
41 + 31576583 = 31576624
83 + 31576541 = 31576624
113 + 31576511 = 31576624
197 + 31576427 = 31576624
251 + 31576373 = 31576624
257 + 31576367 = 31576624
383 + 31576241 = 31576624

Showing the first eight; more decompositions exist.
