Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474636, here are decompositions:

59 + 31474577 = 31474636
233 + 31474403 = 31474636
239 + 31474397 = 31474636
293 + 31474343 = 31474636
317 + 31474319 = 31474636
383 + 31474253 = 31474636
419 + 31474217 = 31474636
563 + 31474073 = 31474636

Showing the first eight; more decompositions exist.
