Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449162, here are decompositions:

79 + 31449083 = 31449162
109 + 31449053 = 31449162
263 + 31448899 = 31449162
271 + 31448891 = 31449162
359 + 31448803 = 31449162
421 + 31448741 = 31449162
443 + 31448719 = 31449162
449 + 31448713 = 31449162

Showing the first eight; more decompositions exist.
