Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598186, here are decompositions:

7 + 31598179 = 31598186
43 + 31598143 = 31598186
157 + 31598029 = 31598186
199 + 31597987 = 31598186
307 + 31597879 = 31598186
313 + 31597873 = 31598186
409 + 31597777 = 31598186
457 + 31597729 = 31598186

Showing the first eight; more decompositions exist.
