Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498446, here are decompositions:

19 + 31498427 = 31498446
79 + 31498367 = 31498446
97 + 31498349 = 31498446
103 + 31498343 = 31498446
139 + 31498307 = 31498446
157 + 31498289 = 31498446
167 + 31498279 = 31498446
173 + 31498273 = 31498446

Showing the first eight; more decompositions exist.
