Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55142, here are decompositions:

163 + 54979 = 55142
193 + 54949 = 55142
223 + 54919 = 55142
313 + 54829 = 55142
421 + 54721 = 55142
433 + 54709 = 55142
463 + 54679 = 55142
541 + 54601 = 55142

Showing the first eight; more decompositions exist.
