Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613626, here are decompositions:

3 + 31613623 = 31613626
47 + 31613579 = 31613626
113 + 31613513 = 31613626
227 + 31613399 = 31613626
269 + 31613357 = 31613626
293 + 31613333 = 31613626
383 + 31613243 = 31613626
509 + 31613117 = 31613626

Showing the first eight; more decompositions exist.
