Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499162, here are decompositions:

3 + 31499159 = 31499162
139 + 31499023 = 31499162
199 + 31498963 = 31499162
283 + 31498879 = 31499162
313 + 31498849 = 31499162
349 + 31498813 = 31499162
421 + 31498741 = 31499162
523 + 31498639 = 31499162

Showing the first eight; more decompositions exist.
