Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552402, here are decompositions:

131 + 31552271 = 31552402
149 + 31552253 = 31552402
173 + 31552229 = 31552402
191 + 31552211 = 31552402
263 + 31552139 = 31552402
353 + 31552049 = 31552402
383 + 31552019 = 31552402
443 + 31551959 = 31552402

Showing the first eight; more decompositions exist.
