Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987846, here are decompositions:

37 + 987809 = 987846
43 + 987803 = 987846
53 + 987793 = 987846
107 + 987739 = 987846
149 + 987697 = 987846
239 + 987607 = 987846
313 + 987533 = 987846
337 + 987509 = 987846

Showing the first eight; more decompositions exist.
