Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480198, here are decompositions:

107 + 31480091 = 31480198
137 + 31480061 = 31480198
149 + 31480049 = 31480198
179 + 31480019 = 31480198
251 + 31479947 = 31480198
317 + 31479881 = 31480198
461 + 31479737 = 31480198
479 + 31479719 = 31480198

Showing the first eight; more decompositions exist.
