Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498248, here are decompositions:

31 + 31498217 = 31498248
59 + 31498189 = 31498248
97 + 31498151 = 31498248
137 + 31498111 = 31498248
179 + 31498069 = 31498248
239 + 31498009 = 31498248
241 + 31498007 = 31498248
251 + 31497997 = 31498248

Showing the first eight; more decompositions exist.
