Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498148, here are decompositions:

37 + 31498111 = 31498148
61 + 31498087 = 31498148
79 + 31498069 = 31498148
109 + 31498039 = 31498148
139 + 31498009 = 31498148
151 + 31497997 = 31498148
277 + 31497871 = 31498148
397 + 31497751 = 31498148

Showing the first eight; more decompositions exist.
