Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446794, here are decompositions:

37 + 31446757 = 31446794
241 + 31446553 = 31446794
367 + 31446427 = 31446794
433 + 31446361 = 31446794
541 + 31446253 = 31446794
571 + 31446223 = 31446794
661 + 31446133 = 31446794
727 + 31446067 = 31446794

Showing the first eight; more decompositions exist.
