Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624408, here are decompositions:

41 + 31624367 = 31624408
59 + 31624349 = 31624408
71 + 31624337 = 31624408
131 + 31624277 = 31624408
191 + 31624217 = 31624408
281 + 31624127 = 31624408
419 + 31623989 = 31624408
449 + 31623959 = 31624408

Showing the first eight; more decompositions exist.
