Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55838, here are decompositions:

19 + 55819 = 55838
31 + 55807 = 55838
127 + 55711 = 55838
157 + 55681 = 55838
199 + 55639 = 55838
229 + 55609 = 55838
337 + 55501 = 55838
397 + 55441 = 55838

Showing the first eight; more decompositions exist.
