Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497092, here are decompositions:

103 + 31496989 = 31497092
229 + 31496863 = 31497092
283 + 31496809 = 31497092
313 + 31496779 = 31497092
373 + 31496719 = 31497092
421 + 31496671 = 31497092
499 + 31496593 = 31497092
541 + 31496551 = 31497092

Showing the first eight; more decompositions exist.
