Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987774, here are decompositions:

61 + 987713 = 987774
167 + 987607 = 987774
181 + 987593 = 987774
233 + 987541 = 987774
241 + 987533 = 987774
251 + 987523 = 987774
283 + 987491 = 987774
311 + 987463 = 987774

Showing the first eight; more decompositions exist.
