Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599350, here are decompositions:

37 + 31599313 = 31599350
43 + 31599307 = 31599350
103 + 31599247 = 31599350
157 + 31599193 = 31599350
193 + 31599157 = 31599350
397 + 31598953 = 31599350
439 + 31598911 = 31599350
463 + 31598887 = 31599350

Showing the first eight; more decompositions exist.
