Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499276, here are decompositions:

37 + 31499239 = 31499276
139 + 31499137 = 31499276
199 + 31499077 = 31499276
283 + 31498993 = 31499276
313 + 31498963 = 31499276
379 + 31498897 = 31499276
397 + 31498879 = 31499276
409 + 31498867 = 31499276

Showing the first eight; more decompositions exist.
