Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498088, here are decompositions:

19 + 31498069 = 31498088
79 + 31498009 = 31498088
109 + 31497979 = 31498088
157 + 31497931 = 31498088
229 + 31497859 = 31498088
331 + 31497757 = 31498088
337 + 31497751 = 31498088
367 + 31497721 = 31498088

Showing the first eight; more decompositions exist.
