Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172124, here are decompositions:

31 + 172093 = 172124
97 + 172027 = 172124
103 + 172021 = 172124
313 + 171811 = 172124
331 + 171793 = 172124
367 + 171757 = 172124
487 + 171637 = 172124
541 + 171583 = 172124

Showing the first eight; more decompositions exist.
