Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543698, here are decompositions:

7 + 31543691 = 31543698
29 + 31543669 = 31543698
37 + 31543661 = 31543698
127 + 31543571 = 31543698
167 + 31543531 = 31543698
269 + 31543429 = 31543698
337 + 31543361 = 31543698
349 + 31543349 = 31543698

Showing the first eight; more decompositions exist.
