Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449136, here are decompositions:

53 + 31449083 = 31449136
83 + 31449053 = 31449136
107 + 31449029 = 31449136
149 + 31448987 = 31449136
227 + 31448909 = 31449136
233 + 31448903 = 31449136
239 + 31448897 = 31449136
419 + 31448717 = 31449136

Showing the first eight; more decompositions exist.
