Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469198, here are decompositions:

67 + 31469131 = 31469198
97 + 31469101 = 31469198
157 + 31469041 = 31469198
337 + 31468861 = 31469198
349 + 31468849 = 31469198
421 + 31468777 = 31469198
499 + 31468699 = 31469198
601 + 31468597 = 31469198

Showing the first eight; more decompositions exist.
