Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522898, here are decompositions:

151 + 31522747 = 31522898
181 + 31522717 = 31522898
229 + 31522669 = 31522898
241 + 31522657 = 31522898
307 + 31522591 = 31522898
349 + 31522549 = 31522898
439 + 31522459 = 31522898
457 + 31522441 = 31522898

Showing the first eight; more decompositions exist.
