Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519276, here are decompositions:

23 + 31519253 = 31519276
29 + 31519247 = 31519276
83 + 31519193 = 31519276
167 + 31519109 = 31519276
227 + 31519049 = 31519276
353 + 31518923 = 31519276
449 + 31518827 = 31519276
599 + 31518677 = 31519276

Showing the first eight; more decompositions exist.
