Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624952, here are decompositions:

13 + 31624939 = 31624952
31 + 31624921 = 31624952
103 + 31624849 = 31624952
199 + 31624753 = 31624952
211 + 31624741 = 31624952
313 + 31624639 = 31624952
523 + 31624429 = 31624952
613 + 31624339 = 31624952

Showing the first eight; more decompositions exist.
