Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455614, here are decompositions:

181 + 31455433 = 31455614
313 + 31455301 = 31455614
643 + 31454971 = 31455614
661 + 31454953 = 31455614
691 + 31454923 = 31455614
733 + 31454881 = 31455614
787 + 31454827 = 31455614
877 + 31454737 = 31455614

Showing the first eight; more decompositions exist.
