Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474684, here are decompositions:

11 + 31474673 = 31474684
83 + 31474601 = 31474684
107 + 31474577 = 31474684
113 + 31474571 = 31474684
251 + 31474433 = 31474684
281 + 31474403 = 31474684
383 + 31474301 = 31474684
431 + 31474253 = 31474684

Showing the first eight; more decompositions exist.
