Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517340, here are decompositions:

67 + 31517273 = 31517340
73 + 31517267 = 31517340
97 + 31517243 = 31517340
109 + 31517231 = 31517340
191 + 31517149 = 31517340
277 + 31517063 = 31517340
313 + 31517027 = 31517340
347 + 31516993 = 31517340

Showing the first eight; more decompositions exist.
