Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986972, here are decompositions:

13 + 986959 = 986972
31 + 986941 = 986972
43 + 986929 = 986972
193 + 986779 = 986972
223 + 986749 = 986972
313 + 986659 = 986972
331 + 986641 = 986972
373 + 986599 = 986972

Showing the first eight; more decompositions exist.
