Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598774, here are decompositions:

3 + 31598771 = 31598774
73 + 31598701 = 31598774
127 + 31598647 = 31598774
373 + 31598401 = 31598774
397 + 31598377 = 31598774
421 + 31598353 = 31598774
547 + 31598227 = 31598774
631 + 31598143 = 31598774

Showing the first eight; more decompositions exist.
