Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613446, here are decompositions:

5 + 31613441 = 31613446
47 + 31613399 = 31613446
89 + 31613357 = 31613446
113 + 31613333 = 31613446
197 + 31613249 = 31613446
419 + 31613027 = 31613446
593 + 31612853 = 31613446
719 + 31612727 = 31613446

Showing the first eight; more decompositions exist.
