Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55538, here are decompositions:

37 + 55501 = 55538
97 + 55441 = 55538
127 + 55411 = 55538
139 + 55399 = 55538
157 + 55381 = 55538
199 + 55339 = 55538
331 + 55207 = 55538
337 + 55201 = 55538

Showing the first eight; more decompositions exist.
