Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61918, here are decompositions:

47 + 61871 = 61918
137 + 61781 = 61918
167 + 61751 = 61918
251 + 61667 = 61918
281 + 61637 = 61918
359 + 61559 = 61918
431 + 61487 = 61918
449 + 61469 = 61918

Showing the first eight; more decompositions exist.
