Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446194, here are decompositions:

61 + 31446133 = 31446194
97 + 31446097 = 31446194
127 + 31446067 = 31446194
163 + 31446031 = 31446194
211 + 31445983 = 31446194
277 + 31445917 = 31446194
331 + 31445863 = 31446194
607 + 31445587 = 31446194

Showing the first eight; more decompositions exist.
