Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18974, here are decompositions:

61 + 18913 = 18974
181 + 18793 = 18974
283 + 18691 = 18974
313 + 18661 = 18974
337 + 18637 = 18974
421 + 18553 = 18974
433 + 18541 = 18974
457 + 18517 = 18974

Showing the first eight; more decompositions exist.
