Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498368, here are decompositions:

19 + 31498349 = 31498368
61 + 31498307 = 31498368
79 + 31498289 = 31498368
89 + 31498279 = 31498368
151 + 31498217 = 31498368
179 + 31498189 = 31498368
257 + 31498111 = 31498368
281 + 31498087 = 31498368

Showing the first eight; more decompositions exist.
