Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517692, here are decompositions:

53 + 31517639 = 31517692
113 + 31517579 = 31517692
149 + 31517543 = 31517692
191 + 31517501 = 31517692
251 + 31517441 = 31517692
281 + 31517411 = 31517692
293 + 31517399 = 31517692
419 + 31517273 = 31517692

Showing the first eight; more decompositions exist.
