Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86974, here are decompositions:

5 + 86969 = 86974
23 + 86951 = 86974
47 + 86927 = 86974
113 + 86861 = 86974
131 + 86843 = 86974
137 + 86837 = 86974
191 + 86783 = 86974
263 + 86711 = 86974

Showing the first eight; more decompositions exist.
