Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499036, here are decompositions:

3 + 31499033 = 31499036
13 + 31499023 = 31499036
43 + 31498993 = 31499036
73 + 31498963 = 31499036
139 + 31498897 = 31499036
157 + 31498879 = 31499036
199 + 31498837 = 31499036
223 + 31498813 = 31499036

Showing the first eight; more decompositions exist.
