Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501830, here are decompositions:

3 + 501827 = 501830
13 + 501817 = 501830
61 + 501769 = 501830
127 + 501703 = 501830
139 + 501691 = 501830
193 + 501637 = 501830
229 + 501601 = 501830
337 + 501493 = 501830

Showing the first eight; more decompositions exist.
