Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586204, here are decompositions:

73 + 31586131 = 31586204
103 + 31586101 = 31586204
127 + 31586077 = 31586204
151 + 31586053 = 31586204
241 + 31585963 = 31586204
367 + 31585837 = 31586204
421 + 31585783 = 31586204
541 + 31585663 = 31586204

Showing the first eight; more decompositions exist.
