Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449364, here are decompositions:

3 + 31449361 = 31449364
5 + 31449359 = 31449364
41 + 31449323 = 31449364
101 + 31449263 = 31449364
131 + 31449233 = 31449364
173 + 31449191 = 31449364
281 + 31449083 = 31449364
293 + 31449071 = 31449364

Showing the first eight; more decompositions exist.
