Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511852, here are decompositions:

79 + 31511773 = 31511852
109 + 31511743 = 31511852
139 + 31511713 = 31511852
199 + 31511653 = 31511852
241 + 31511611 = 31511852
283 + 31511569 = 31511852
313 + 31511539 = 31511852
349 + 31511503 = 31511852

Showing the first eight; more decompositions exist.
