Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450, here are decompositions:

53 + 31397 = 31450
59 + 31391 = 31450
71 + 31379 = 31450
113 + 31337 = 31450
131 + 31319 = 31450
173 + 31277 = 31450
179 + 31271 = 31450
191 + 31259 = 31450

Showing the first eight; more decompositions exist.
