Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592318, here are decompositions:

7 + 31592311 = 31592318
61 + 31592257 = 31592318
157 + 31592161 = 31592318
271 + 31592047 = 31592318
409 + 31591909 = 31592318
607 + 31591711 = 31592318
631 + 31591687 = 31592318
937 + 31591381 = 31592318

Showing the first eight; more decompositions exist.
