Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498614, here are decompositions:

23 + 31498591 = 31498614
67 + 31498547 = 31498614
73 + 31498541 = 31498614
97 + 31498517 = 31498614
101 + 31498513 = 31498614
151 + 31498463 = 31498614
193 + 31498421 = 31498614
271 + 31498343 = 31498614

Showing the first eight; more decompositions exist.
