Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454190, here are decompositions:

29 + 31454161 = 31454190
41 + 31454149 = 31454190
43 + 31454147 = 31454190
67 + 31454123 = 31454190
73 + 31454117 = 31454190
107 + 31454083 = 31454190
109 + 31454081 = 31454190
113 + 31454077 = 31454190

Showing the first eight; more decompositions exist.
