Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498714, here are decompositions:

11 + 31498703 = 31498714
167 + 31498547 = 31498714
173 + 31498541 = 31498714
197 + 31498517 = 31498714
251 + 31498463 = 31498714
293 + 31498421 = 31498714
347 + 31498367 = 31498714
461 + 31498253 = 31498714

Showing the first eight; more decompositions exist.
