Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453924, here are decompositions:

41 + 31453883 = 31453924
83 + 31453841 = 31453924
101 + 31453823 = 31453924
191 + 31453733 = 31453924
197 + 31453727 = 31453924
347 + 31453577 = 31453924
353 + 31453571 = 31453924
401 + 31453523 = 31453924

Showing the first eight; more decompositions exist.
