Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499076, here are decompositions:

13 + 31499063 = 31499076
19 + 31499057 = 31499076
43 + 31499033 = 31499076
53 + 31499023 = 31499076
73 + 31499003 = 31499076
83 + 31498993 = 31499076
109 + 31498967 = 31499076
113 + 31498963 = 31499076

Showing the first eight; more decompositions exist.
