Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626124, here are decompositions:

71 + 31626053 = 31626124
83 + 31626041 = 31626124
113 + 31626011 = 31626124
137 + 31625987 = 31626124
281 + 31625843 = 31626124
317 + 31625807 = 31626124
347 + 31625777 = 31626124
401 + 31625723 = 31626124

Showing the first eight; more decompositions exist.
