Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588700, here are decompositions:

7 + 31588693 = 31588700
43 + 31588657 = 31588700
97 + 31588603 = 31588700
139 + 31588561 = 31588700
229 + 31588471 = 31588700
331 + 31588369 = 31588700
349 + 31588351 = 31588700
379 + 31588321 = 31588700

Showing the first eight; more decompositions exist.
