Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522758, here are decompositions:

11 + 31522747 = 31522758
41 + 31522717 = 31522758
89 + 31522669 = 31522758
101 + 31522657 = 31522758
167 + 31522591 = 31522758
229 + 31522529 = 31522758
307 + 31522451 = 31522758
317 + 31522441 = 31522758

Showing the first eight; more decompositions exist.
