Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90372, here are decompositions:

13 + 90359 = 90372
19 + 90353 = 90372
59 + 90313 = 90372
83 + 90289 = 90372
101 + 90271 = 90372
109 + 90263 = 90372
173 + 90199 = 90372
181 + 90191 = 90372

Showing the first eight; more decompositions exist.
