Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987854, here are decompositions:

3 + 987851 = 987854
61 + 987793 = 987854
157 + 987697 = 987854
223 + 987631 = 987854
313 + 987541 = 987854
331 + 987523 = 987854
397 + 987457 = 987854
421 + 987433 = 987854

Showing the first eight; more decompositions exist.
