Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987852, here are decompositions:

31 + 987821 = 987852
43 + 987809 = 987852
59 + 987793 = 987852
113 + 987739 = 987852
139 + 987713 = 987852
193 + 987659 = 987852
293 + 987559 = 987852
311 + 987541 = 987852

Showing the first eight; more decompositions exist.
