Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535374, here are decompositions:

47 + 31535327 = 31535374
53 + 31535321 = 31535374
191 + 31535183 = 31535374
251 + 31535123 = 31535374
293 + 31535081 = 31535374
317 + 31535057 = 31535374
461 + 31534913 = 31535374
503 + 31534871 = 31535374

Showing the first eight; more decompositions exist.
