Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481592, here are decompositions:

61 + 31481531 = 31481592
71 + 31481521 = 31481592
83 + 31481509 = 31481592
113 + 31481479 = 31481592
139 + 31481453 = 31481592
173 + 31481419 = 31481592
199 + 31481393 = 31481592
223 + 31481369 = 31481592

Showing the first eight; more decompositions exist.
