Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449586, here are decompositions:

5 + 31449581 = 31449586
17 + 31449569 = 31449586
29 + 31449557 = 31449586
59 + 31449527 = 31449586
107 + 31449479 = 31449586
137 + 31449449 = 31449586
227 + 31449359 = 31449586
263 + 31449323 = 31449586

Showing the first eight; more decompositions exist.
