Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997282, here are decompositions:

3 + 997279 = 997282
23 + 997259 = 997282
131 + 997151 = 997282
173 + 997109 = 997282
179 + 997103 = 997282
191 + 997091 = 997282
239 + 997043 = 997282
263 + 997019 = 997282

Showing the first eight; more decompositions exist.
