Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7312, here are decompositions:

3 + 7309 = 7312
5 + 7307 = 7312
29 + 7283 = 7312
59 + 7253 = 7312
83 + 7229 = 7312
101 + 7211 = 7312
191 + 7121 = 7312
233 + 7079 = 7312

Showing the first eight; more decompositions exist.
