Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498558, here are decompositions:

11 + 31498547 = 31498558
17 + 31498541 = 31498558
29 + 31498529 = 31498558
41 + 31498517 = 31498558
59 + 31498499 = 31498558
89 + 31498469 = 31498558
131 + 31498427 = 31498558
137 + 31498421 = 31498558

Showing the first eight; more decompositions exist.
