Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552480, here are decompositions:

59 + 31552421 = 31552480
227 + 31552253 = 31552480
251 + 31552229 = 31552480
269 + 31552211 = 31552480
353 + 31552127 = 31552480
431 + 31552049 = 31552480
461 + 31552019 = 31552480
503 + 31551977 = 31552480

Showing the first eight; more decompositions exist.
