Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499654, here are decompositions:

61 + 31499593 = 31499654
157 + 31499497 = 31499654
163 + 31499491 = 31499654
223 + 31499431 = 31499654
271 + 31499383 = 31499654
283 + 31499371 = 31499654
313 + 31499341 = 31499654
331 + 31499323 = 31499654

Showing the first eight; more decompositions exist.
