Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450060, here are decompositions:

3 + 31450057 = 31450060
17 + 31450043 = 31450060
29 + 31450031 = 31450060
71 + 31449989 = 31450060
137 + 31449923 = 31450060
269 + 31449791 = 31450060
293 + 31449767 = 31450060
359 + 31449701 = 31450060

Showing the first eight; more decompositions exist.
