Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472614, here are decompositions:

3 + 31472611 = 31472614
23 + 31472591 = 31472614
113 + 31472501 = 31472614
263 + 31472351 = 31472614
353 + 31472261 = 31472614
431 + 31472183 = 31472614
461 + 31472153 = 31472614
491 + 31472123 = 31472614

Showing the first eight; more decompositions exist.
