Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987974, here are decompositions:

3 + 987971 = 987974
61 + 987913 = 987974
181 + 987793 = 987974
277 + 987697 = 987974
367 + 987607 = 987974
433 + 987541 = 987974
541 + 987433 = 987974
613 + 987361 = 987974

Showing the first eight; more decompositions exist.
