Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474598, here are decompositions:

79 + 31474519 = 31474598
97 + 31474501 = 31474598
109 + 31474489 = 31474598
241 + 31474357 = 31474598
307 + 31474291 = 31474598
349 + 31474249 = 31474598
457 + 31474141 = 31474598
487 + 31474111 = 31474598

Showing the first eight; more decompositions exist.
