Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981964, here are decompositions:

3 + 981961 = 981964
17 + 981947 = 981964
23 + 981941 = 981964
167 + 981797 = 981964
233 + 981731 = 981964
251 + 981713 = 981964
257 + 981707 = 981964
281 + 981683 = 981964

Showing the first eight; more decompositions exist.
