Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987932, here are decompositions:

3 + 987929 = 987932
19 + 987913 = 987932
139 + 987793 = 987932
193 + 987739 = 987932
373 + 987559 = 987932
409 + 987523 = 987932
499 + 987433 = 987932
541 + 987391 = 987932

Showing the first eight; more decompositions exist.
