Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498684, here are decompositions:

137 + 31498547 = 31498684
167 + 31498517 = 31498684
257 + 31498427 = 31498684
263 + 31498421 = 31498684
317 + 31498367 = 31498684
431 + 31498253 = 31498684
467 + 31498217 = 31498684
491 + 31498193 = 31498684

Showing the first eight; more decompositions exist.
