Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448150, here are decompositions:

79 + 31448071 = 31448150
127 + 31448023 = 31448150
163 + 31447987 = 31448150
193 + 31447957 = 31448150
199 + 31447951 = 31448150
313 + 31447837 = 31448150
337 + 31447813 = 31448150
367 + 31447783 = 31448150

Showing the first eight; more decompositions exist.
