Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474424, here are decompositions:

61 + 31474363 = 31474424
67 + 31474357 = 31474424
73 + 31474351 = 31474424
211 + 31474213 = 31474424
283 + 31474141 = 31474424
313 + 31474111 = 31474424
367 + 31474057 = 31474424
433 + 31473991 = 31474424

Showing the first eight; more decompositions exist.
