Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599246, here are decompositions:

53 + 31599193 = 31599246
73 + 31599173 = 31599246
89 + 31599157 = 31599246
257 + 31598989 = 31599246
293 + 31598953 = 31599246
307 + 31598939 = 31599246
313 + 31598933 = 31599246
337 + 31598909 = 31599246

Showing the first eight; more decompositions exist.
