Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55442, here are decompositions:

3 + 55439 = 55442
31 + 55411 = 55442
43 + 55399 = 55442
61 + 55381 = 55442
103 + 55339 = 55442
109 + 55333 = 55442
151 + 55291 = 55442
193 + 55249 = 55442

Showing the first eight; more decompositions exist.
