Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553876, here are decompositions:

43 + 31553833 = 31553876
73 + 31553803 = 31553876
157 + 31553719 = 31553876
349 + 31553527 = 31553876
373 + 31553503 = 31553876
643 + 31553233 = 31553876
787 + 31553089 = 31553876
859 + 31553017 = 31553876

Showing the first eight; more decompositions exist.
