Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540300, here are decompositions:

3 + 31540297 = 31540300
59 + 31540241 = 31540300
83 + 31540217 = 31540300
89 + 31540211 = 31540300
137 + 31540163 = 31540300
191 + 31540109 = 31540300
269 + 31540031 = 31540300
293 + 31540007 = 31540300

Showing the first eight; more decompositions exist.
