Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446926, here are decompositions:

67 + 31446859 = 31446926
73 + 31446853 = 31446926
79 + 31446847 = 31446926
157 + 31446769 = 31446926
373 + 31446553 = 31446926
487 + 31446439 = 31446926
499 + 31446427 = 31446926
673 + 31446253 = 31446926

Showing the first eight; more decompositions exist.
