Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590248, here are decompositions:

7 + 31590241 = 31590248
37 + 31590211 = 31590248
61 + 31590187 = 31590248
127 + 31590121 = 31590248
211 + 31590037 = 31590248
241 + 31590007 = 31590248
271 + 31589977 = 31590248
379 + 31589869 = 31590248

Showing the first eight; more decompositions exist.
