Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541796, here are decompositions:

59 + 31541737 = 31541796
89 + 31541707 = 31541796
103 + 31541693 = 31541796
137 + 31541659 = 31541796
163 + 31541633 = 31541796
199 + 31541597 = 31541796
227 + 31541569 = 31541796
233 + 31541563 = 31541796

Showing the first eight; more decompositions exist.
