Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45242, here are decompositions:

61 + 45181 = 45242
103 + 45139 = 45242
181 + 45061 = 45242
229 + 45013 = 45242
271 + 44971 = 45242
283 + 44959 = 45242
349 + 44893 = 45242
433 + 44809 = 45242

Showing the first eight; more decompositions exist.
