Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448260, here are decompositions:

59 + 31448201 = 31448260
89 + 31448171 = 31448260
149 + 31448111 = 31448260
191 + 31448069 = 31448260
227 + 31448033 = 31448260
293 + 31447967 = 31448260
359 + 31447901 = 31448260
449 + 31447811 = 31448260

Showing the first eight; more decompositions exist.
