Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498436, here are decompositions:

157 + 31498279 = 31498436
163 + 31498273 = 31498436
223 + 31498213 = 31498436
313 + 31498123 = 31498436
349 + 31498087 = 31498436
367 + 31498069 = 31498436
397 + 31498039 = 31498436
433 + 31498003 = 31498436

Showing the first eight; more decompositions exist.
