Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492172, here are decompositions:

59 + 492113 = 492172
89 + 492083 = 492172
113 + 492059 = 492172
353 + 491819 = 492172
383 + 491789 = 492172
389 + 491783 = 492172
503 + 491669 = 492172
521 + 491651 = 492172

Showing the first eight; more decompositions exist.
