Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613706, here are decompositions:

37 + 31613669 = 31613706
67 + 31613639 = 31613706
79 + 31613627 = 31613706
83 + 31613623 = 31613706
127 + 31613579 = 31613706
167 + 31613539 = 31613706
193 + 31613513 = 31613706
269 + 31613437 = 31613706

Showing the first eight; more decompositions exist.
