Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90818, here are decompositions:

31 + 90787 = 90818
109 + 90709 = 90818
139 + 90679 = 90818
199 + 90619 = 90818
271 + 90547 = 90818
307 + 90511 = 90818
337 + 90481 = 90818
349 + 90469 = 90818

Showing the first eight; more decompositions exist.
