Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548998, here are decompositions:

37 + 31548961 = 31548998
127 + 31548871 = 31548998
181 + 31548817 = 31548998
241 + 31548757 = 31548998
379 + 31548619 = 31548998
421 + 31548577 = 31548998
499 + 31548499 = 31548998
571 + 31548427 = 31548998

Showing the first eight; more decompositions exist.
