Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599254, here are decompositions:

7 + 31599247 = 31599254
61 + 31599193 = 31599254
97 + 31599157 = 31599254
151 + 31599103 = 31599254
307 + 31598947 = 31599254
331 + 31598923 = 31599254
367 + 31598887 = 31599254
397 + 31598857 = 31599254

Showing the first eight; more decompositions exist.
