Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986140, here are decompositions:

3 + 986137 = 986140
149 + 985991 = 986140
167 + 985973 = 986140
263 + 985877 = 986140
269 + 985871 = 986140
359 + 985781 = 986140
431 + 985709 = 986140
461 + 985679 = 986140

Showing the first eight; more decompositions exist.
