Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18854, here are decompositions:

61 + 18793 = 18854
67 + 18787 = 18854
97 + 18757 = 18854
163 + 18691 = 18854
193 + 18661 = 18854
271 + 18583 = 18854
313 + 18541 = 18854
331 + 18523 = 18854

Showing the first eight; more decompositions exist.
