Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552330, here are decompositions:

59 + 31552271 = 31552330
101 + 31552229 = 31552330
137 + 31552193 = 31552330
191 + 31552139 = 31552330
281 + 31552049 = 31552330
311 + 31552019 = 31552330
353 + 31551977 = 31552330
389 + 31551941 = 31552330

Showing the first eight; more decompositions exist.
