Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462624, here are decompositions:

41 + 31462583 = 31462624
47 + 31462577 = 31462624
71 + 31462553 = 31462624
173 + 31462451 = 31462624
191 + 31462433 = 31462624
251 + 31462373 = 31462624
311 + 31462313 = 31462624
491 + 31462133 = 31462624

Showing the first eight; more decompositions exist.
