Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499066, here are decompositions:

3 + 31499063 = 31499066
43 + 31499023 = 31499066
73 + 31498993 = 31499066
103 + 31498963 = 31499066
199 + 31498867 = 31499066
229 + 31498837 = 31499066
409 + 31498657 = 31499066
787 + 31498279 = 31499066

Showing the first eight; more decompositions exist.
