Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474418, here are decompositions:

61 + 31474357 = 31474418
67 + 31474351 = 31474418
127 + 31474291 = 31474418
277 + 31474141 = 31474418
307 + 31474111 = 31474418
487 + 31473931 = 31474418
571 + 31473847 = 31474418
607 + 31473811 = 31474418

Showing the first eight; more decompositions exist.
