Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598580, here are decompositions:

37 + 31598543 = 31598580
43 + 31598537 = 31598580
59 + 31598521 = 31598580
61 + 31598519 = 31598580
67 + 31598513 = 31598580
131 + 31598449 = 31598580
157 + 31598423 = 31598580
163 + 31598417 = 31598580

Showing the first eight; more decompositions exist.
