Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613926, here are decompositions:

59 + 31613867 = 31613926
83 + 31613843 = 31613926
107 + 31613819 = 31613926
257 + 31613669 = 31613926
347 + 31613579 = 31613926
569 + 31613357 = 31613926
593 + 31613333 = 31613926
677 + 31613249 = 31613926

Showing the first eight; more decompositions exist.
