Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997242, here are decompositions:

23 + 997219 = 997242
41 + 997201 = 997242
79 + 997163 = 997242
89 + 997153 = 997242
101 + 997141 = 997242
131 + 997111 = 997242
139 + 997103 = 997242
151 + 997091 = 997242

Showing the first eight; more decompositions exist.
