Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499694, here are decompositions:

73 + 31499621 = 31499694
101 + 31499593 = 31499694
157 + 31499537 = 31499694
197 + 31499497 = 31499694
227 + 31499467 = 31499694
263 + 31499431 = 31499694
283 + 31499411 = 31499694
293 + 31499401 = 31499694

Showing the first eight; more decompositions exist.
