Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581202, here are decompositions:

5 + 581197 = 581202
19 + 581183 = 581202
29 + 581173 = 581202
31 + 581171 = 581202
53 + 581149 = 581202
59 + 581143 = 581202
101 + 581101 = 581202
103 + 581099 = 581202

Showing the first eight; more decompositions exist.
