Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613766, here are decompositions:

47 + 31613719 = 31613766
97 + 31613669 = 31613766
127 + 31613639 = 31613766
137 + 31613629 = 31613766
139 + 31613627 = 31613766
227 + 31613539 = 31613766
367 + 31613399 = 31613766
383 + 31613383 = 31613766

Showing the first eight; more decompositions exist.
