Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624774, here are decompositions:

11 + 31624763 = 31624774
101 + 31624673 = 31624774
113 + 31624661 = 31624774
131 + 31624643 = 31624774
227 + 31624547 = 31624774
263 + 31624511 = 31624774
317 + 31624457 = 31624774
431 + 31624343 = 31624774

Showing the first eight; more decompositions exist.
