Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2242, here are decompositions:

3 + 2239 = 2242
5 + 2237 = 2242
29 + 2213 = 2242
89 + 2153 = 2242
101 + 2141 = 2242
113 + 2129 = 2242
131 + 2111 = 2242
173 + 2069 = 2242

Showing the first eight; more decompositions exist.
