Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624444, here are decompositions:

101 + 31624343 = 31624444
107 + 31624337 = 31624444
113 + 31624331 = 31624444
167 + 31624277 = 31624444
227 + 31624217 = 31624444
317 + 31624127 = 31624444
431 + 31624013 = 31624444
443 + 31624001 = 31624444

Showing the first eight; more decompositions exist.
