Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499580, here are decompositions:

31 + 499549 = 499580
61 + 499519 = 499580
73 + 499507 = 499580
97 + 499483 = 499580
157 + 499423 = 499580
271 + 499309 = 499580
313 + 499267 = 499580
397 + 499183 = 499580

Showing the first eight; more decompositions exist.
