Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494952, here are decompositions:

3 + 31494949 = 31494952
29 + 31494923 = 31494952
239 + 31494713 = 31494952
263 + 31494689 = 31494952
443 + 31494509 = 31494952
449 + 31494503 = 31494952
509 + 31494443 = 31494952
521 + 31494431 = 31494952

Showing the first eight; more decompositions exist.
