Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581204, here are decompositions:

3 + 581201 = 581204
7 + 581197 = 581204
31 + 581173 = 581204
61 + 581143 = 581204
67 + 581137 = 581204
103 + 581101 = 581204
157 + 581047 = 581204
163 + 581041 = 581204

Showing the first eight; more decompositions exist.
