Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552372, here are decompositions:

101 + 31552271 = 31552372
179 + 31552193 = 31552372
233 + 31552139 = 31552372
353 + 31552019 = 31552372
431 + 31551941 = 31552372
569 + 31551803 = 31552372
701 + 31551671 = 31552372
743 + 31551629 = 31552372

Showing the first eight; more decompositions exist.
