Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598300, here are decompositions:

61 + 31598239 = 31598300
73 + 31598227 = 31598300
109 + 31598191 = 31598300
157 + 31598143 = 31598300
163 + 31598137 = 31598300
199 + 31598101 = 31598300
271 + 31598029 = 31598300
313 + 31597987 = 31598300

Showing the first eight; more decompositions exist.
