Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698142, here are decompositions:

31 + 8698111 = 8698142
199 + 8697943 = 8698142
223 + 8697919 = 8698142
241 + 8697901 = 8698142
283 + 8697859 = 8698142
331 + 8697811 = 8698142
373 + 8697769 = 8698142
631 + 8697511 = 8698142

Showing the first eight; more decompositions exist.
