Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498328, here are decompositions:

139 + 31498189 = 31498328
241 + 31498087 = 31498328
331 + 31497997 = 31498328
349 + 31497979 = 31498328
397 + 31497931 = 31498328
457 + 31497871 = 31498328
571 + 31497757 = 31498328
577 + 31497751 = 31498328

Showing the first eight; more decompositions exist.
