Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498654, here are decompositions:

107 + 31498547 = 31498654
113 + 31498541 = 31498654
137 + 31498517 = 31498654
191 + 31498463 = 31498654
227 + 31498427 = 31498654
233 + 31498421 = 31498654
311 + 31498343 = 31498654
347 + 31498307 = 31498654

Showing the first eight; more decompositions exist.
