Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624452, here are decompositions:

23 + 31624429 = 31624452
29 + 31624423 = 31624452
89 + 31624363 = 31624452
103 + 31624349 = 31624452
109 + 31624343 = 31624452
113 + 31624339 = 31624452
131 + 31624321 = 31624452
311 + 31624141 = 31624452

Showing the first eight; more decompositions exist.
