Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529798, here are decompositions:

127 + 31529671 = 31529798
241 + 31529557 = 31529798
277 + 31529521 = 31529798
367 + 31529431 = 31529798
439 + 31529359 = 31529798
541 + 31529257 = 31529798
631 + 31529167 = 31529798
691 + 31529107 = 31529798

Showing the first eight; more decompositions exist.
