Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474586, here are decompositions:

37 + 31474549 = 31474586
67 + 31474519 = 31474586
97 + 31474489 = 31474586
163 + 31474423 = 31474586
223 + 31474363 = 31474586
229 + 31474357 = 31474586
337 + 31474249 = 31474586
373 + 31474213 = 31474586

Showing the first eight; more decompositions exist.
