Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523972, here are decompositions:

3 + 523969 = 523972
23 + 523949 = 523972
179 + 523793 = 523972
401 + 523571 = 523972
419 + 523553 = 523972
431 + 523541 = 523972
461 + 523511 = 523972
479 + 523493 = 523972

Showing the first eight; more decompositions exist.
