Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613776, here are decompositions:

59 + 31613717 = 31613776
107 + 31613669 = 31613776
137 + 31613639 = 31613776
149 + 31613627 = 31613776
197 + 31613579 = 31613776
263 + 31613513 = 31613776
419 + 31613357 = 31613776
443 + 31613333 = 31613776

Showing the first eight; more decompositions exist.
