Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448982, here are decompositions:

73 + 31448909 = 31448982
79 + 31448903 = 31448982
83 + 31448899 = 31448982
179 + 31448803 = 31448982
241 + 31448741 = 31448982
263 + 31448719 = 31448982
269 + 31448713 = 31448982
283 + 31448699 = 31448982

Showing the first eight; more decompositions exist.
