Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543758, here are decompositions:

7 + 31543751 = 31543758
47 + 31543711 = 31543758
61 + 31543697 = 31543758
67 + 31543691 = 31543758
89 + 31543669 = 31543758
97 + 31543661 = 31543758
179 + 31543579 = 31543758
227 + 31543531 = 31543758

Showing the first eight; more decompositions exist.
