Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446120, here are decompositions:

19 + 31446101 = 31446120
23 + 31446097 = 31446120
53 + 31446067 = 31446120
59 + 31446061 = 31446120
67 + 31446053 = 31446120
89 + 31446031 = 31446120
109 + 31446011 = 31446120
137 + 31445983 = 31446120

Showing the first eight; more decompositions exist.
