Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462750, here are decompositions:

3 + 31462747 = 31462750
101 + 31462649 = 31462750
167 + 31462583 = 31462750
173 + 31462577 = 31462750
197 + 31462553 = 31462750
269 + 31462481 = 31462750
311 + 31462439 = 31462750
317 + 31462433 = 31462750

Showing the first eight; more decompositions exist.
