Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494884, here are decompositions:

67 + 31494817 = 31494884
103 + 31494781 = 31494884
163 + 31494721 = 31494884
193 + 31494691 = 31494884
241 + 31494643 = 31494884
331 + 31494553 = 31494884
457 + 31494427 = 31494884
643 + 31494241 = 31494884

Showing the first eight; more decompositions exist.
