Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508706, here are decompositions:

23 + 31508683 = 31508706
29 + 31508677 = 31508706
59 + 31508647 = 31508706
67 + 31508639 = 31508706
127 + 31508579 = 31508706
137 + 31508569 = 31508706
139 + 31508567 = 31508706
149 + 31508557 = 31508706

Showing the first eight; more decompositions exist.
