Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576504, here are decompositions:

101 + 31576403 = 31576504
131 + 31576373 = 31576504
137 + 31576367 = 31576504
251 + 31576253 = 31576504
263 + 31576241 = 31576504
293 + 31576211 = 31576504
317 + 31576187 = 31576504
383 + 31576121 = 31576504

Showing the first eight; more decompositions exist.
